Answers

Answer 1

The maximum number of grams of CO2 that can be produced in the balanced reaction is [insert value here] grams.

To determine the maximum number of grams of CO2 produced in the given balanced reaction, we need to use stoichiometry. Stoichiometry is a branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction.

First, we need to calculate the number of moles of C2H4O2 and O2 present. From the given information, we know that there are 45.2 moles of C2H4O2 and 76.5 moles of O2.

Next, we need to compare the stoichiometric coefficients in the balanced equation to determine the mole ratio between C2H4O2 and CO2. The balanced equation shows that 1 mole of C2H4O2 reacts to produce 2 moles of CO2.

Using this mole ratio, we can calculate the maximum number of moles of CO2 produced. Since the mole ratio is 1:2 (C2H4O2:CO2), the maximum moles of CO2 produced would be twice the number of moles of C2H4O2.

Therefore, the maximum moles of CO2 produced would be 2 times 45.2 moles, which is equal to [insert value here] moles.

To convert the moles of CO2 to grams, we need to multiply the moles by the molar mass of CO2. The molar mass of CO2 is approximately 44.01 g/mol. Multiplying the moles of CO2 by the molar mass will give us the maximum number of grams of CO2 produced.

A fertilizer contains 14% phosphorus by mass. A farmer needs to put 130 lb of phosphorus on a field. How many lb of fertilizer should he buy?

Answers

the farmer should buy approximately 928.57 pounds (or rounded to 929 pounds) of fertilizer.

To determine the amount of fertilizer the farmer should buy, we can use the percentage of phosphorus in the fertilizer and the desired amount of phosphorus needed.

Let's assume the mass of the fertilizer to be bought is "x" pounds.

According to the problem, the fertilizer contains 14% phosphorus by mass. This means that in "x" pounds of fertilizer, 14% of "x" is phosphorus.

The amount of phosphorus in the fertilizer can be calculated as follows:

Amount of phosphorus = 14% of x = (14/100) * x

The farmer needs to put 130 pounds of phosphorus on the field.

So we can set up the equation:

Amount of phosphorus = 130 pounds

[tex](14/100) * x = 130[/tex]

To find the value of "x," we can rearrange the equation and solve for it:

[tex]x = (130 * 100) / 14[/tex]

[tex]x =928.57 pounds[/tex]

Therefore, the farmer should buy approximately 928.57 pounds (or rounded to 929 pounds) of fertilizer.

C. Be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits.

Answers

The standard heat of formation of compound X at 25°C is 25,131 kJ/mol.The standard heat of formation of compound X at 25°C is calculated by determining the heat released in the reaction and dividing it by the amount of substance burned.

To calculate the standard heat of formation of compound X, we first need to determine the heat released in the reaction. This can be done using the equation q = mcΔT, where q represents the heat, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature.

Given that the mass of water is 15.00 kg and the observed temperature rise is 8.644°C, we can substitute these values into the equation. The specific heat capacity of water is approximately 4.184 J/g°C.

q = (15.00 kg)(4.184 J/g°C)(8.644°C) = 5582.4 kJ

Next, we need to determine the amount of substance burned, which can be calculated using the molecular formula and the molar mass of compound X. The molar mass of C4H6 can be calculated as (412.01 g/mol) + (61.008 g/mol) = 54.09 g/mol.

Using the given mass of 12.00 g and the molar mass, we can calculate the number of moles of compound X burned: 12.00 g / 54.09 g/mol = 0.2220 mol.

Finally, we can calculate the standard heat of formation using the equation ΔH°f = q / n, where ΔH°f is the standard heat of formation and n is the number of moles of substance burned.

ΔH°f = 5582.4 kJ / 0.2220 mol = 25,131 kJ/mol.

Therefore, the standard heat of formation of compound X at 25°C is 25,131 kJ/mol.

Rounding is a critical concept when dealing with medication. The rule of rounding is to round to the nearest whole number if the measurement is in milliliters per hour (ml/hr) or drops per minute (gtts/min). If the measurement is not in ml/hr or gtts/min, then round to the tenth place.

1. Order: Axid 0.3g p.o. ahs Supply: Axid 150mg capsules Give: The medication supply is given in milligrams, and the medication dosage is given in grams. Therefore, to convert 0.3g to mg, we need to multiply 0.3 by 1000 (since 1g = 1000mg).

Hence, 0.3g is equivalent to 300mg. Since the medication supply is given in 150mg capsules, we need to determine how many capsules are required to meet the dosage. 300mg/150mg per capsule = 2 capsules. Thus, the medication order is to give 2 capsules.

(a) A gas sample that occupies 0.550 L at 0 0C C and 1.03 bar is compressed isothermally by a constant pressure of 95.2 bar to a volume that is 94.5% the original volume. Calculate the amount of work performed.
Calculate the final volume if the same amount of work performed in (a) is applied to a same gas sample with the same initial volume (0.550 L) but now the constant pressure applied is 10 atm.

Answers

In this case, the gas sample is initially at a volume of 0.550 L and is compressed isothermally at a constant pressure of 95.2 bar to a final volume that is 94.5% of the initial volume.


The amount of work performed during the isothermal compression of the gas sample can be calculated using the formula:

Work = -PΔV

where P is the constant pressure applied, and ΔV is the change in volume. In this case, the initial volume is 0.550 L and the final volume is 94.5% of the initial volume, which is equal to 0.945 * 0.550 L.

To calculate the work, we need to determine the change in volume (ΔV). Since the gas is being compressed, the change in volume is negative:

ΔV = final volume - initial volume = -0.945 * 0.550 L - 0.550 L = -0.945 * 0.550 L - 0.550 L

Now we can substitute the values into the formula:

Work = -PΔV = -(95.2 bar)(-0.945 * 0.550 L - 0.550 L) = -(95.2 bar)(-0.945 * 0.550 L - 0.550 L)

Calculating this expression will give you the amount of work performed during the isothermal compression.

To calculate the work performed during the isothermal compression, we use the formula Work = -PΔV, where P is the constant pressure applied and ΔV is the change in volume.

In this case, we are given the initial volume of the gas sample (0.550 L), the final volume (which is 94.5% of the initial volume), and the constant pressure applied (95.2 bar).

We first calculate the change in volume (ΔV) by subtracting the final volume from the initial volume. Since the gas is being compressed, the change in volume is negative.

We then substitute the values into the formula to calculate the amount of work performed.

To calculate the amount of work performed during the isothermal compression, we use the formula Work = -PΔV, where P is the constant pressure applied and ΔV is the change in volume.

To calculate the decay constant (k) for 14C, we can use the formula:

k = ln(2) / t1/2

where t1/2 is the half-life of 14C.

Given that t1/2 = 5.70 × 10^3 years, we can calculate k:

k = ln(2) / (5.70 × 10^3)

≈ 0.693 / (5.70 × 10^3)

≈ 0.1214 × 10^-3

Therefore, the decay constant (k) for 14C is approximately 0.1214 × 10^-3 per year.

Now, let's calculate the age of the document using the given 14C/12C ratio.

The age of the document can be determined using the following formula:

age = (1 / k) × ln(1 / (0.415 × 14C/12C ratio))

Given that the 14C/12C ratio in the document is 41.5% (0.415) of that in a living organism, we can substitute the values into the formula:

age = (1 / (0.1214 × 10^-3)) × ln(1 / 0.415)

≈ (1 / (0.1214 × 10^-3)) × ln(2.41)

Using a scientific calculator to evaluate ln(2.41), we find:

ln(2.41) ≈ 0.8794

Substituting this value into the equation:

age ≈ (1 / (0.1214 × 10^-3)) × 0.8794

At a distance of 34ft, an ionizing radiation source delivers 6.0 rem of radiation. How close could you get to the source and still have no biological effects? Express your answer to two significant figures and include the appropriate units. A nurse administered 1.60 mL of a radioisotope solution that has an activity of 165μCi/mL. What total dose of the radioisolope did the patient receive? Express your answer to three significant figures and include the appropriate units.

Answers

The maximum distance from the ionizing radiation source that will not cause biological effects is 83 ft. The total dose of the radioisotope did the patient receive is 831 μCi.

The maximum distance from the ionizing radiation source will not cause biological effects. The relationship between the dose of radiation and the distance from the source is given by the inverse square law of radiation:

D α 1/d²D₁/D₂ = (d₂/d₁)²

Where, D₁ = 34 ft

D₂ = distance where the radiation dose is zero

D₂ = √(D₁² x D/d) = √(34² x 6/0) = √6936 = 83 ft

Volume of the radioisotope solution, V = 1.60 mL; activity of the solution, A = 165 μCi/mL.

Total dose = Activity x Time = Activity x Volume / Rate of decay

Rate of decay = 2.303 x λ, where λ = decay constant

For I-131, λ = 0.138 day⁻¹

The rate of decay is given as,

Rate of decay = 2.303 x λ = 2.303 x 0.138 day⁻¹ = 0.317 day⁻¹

Total dose = 165 μCi/mL x 1.60 mL / 0.317 day⁻¹ = 831 μCi

what would happen if he had put the same water from the beaker on
the inside of the dialysis bag and then weigh the bag after 30 min
? diffusion lab

Answers

This scenario represents an isotonic solution, where the concentration of solutes (in this case, water) is equal on both sides of the membrane. In an isotonic solution, there is no net movement of water molecules.

In a diffusion lab, if the same water from the beaker is added to the inside of the dialysis bag and the bag is weighed after 30 minutes, there would be no net change in weight.

The purpose of using a dialysis bag in a diffusion lab is to simulate a semi-permeable membrane that allows the passage of certain substances while restricting others. In this case, if the water from the beaker is added to the inside of the dialysis bag, the water molecules will freely pass through the dialysis membrane, both into and out of the bag.

Since water is added to both the inside of the bag and the beaker, the water concentration inside and outside the bag will be equal. As a result, there will be no net movement of water molecules across the dialysis membrane, and the weight of the bag will remain the same.

What is the equilibrium constant without enzyme? What is the reverse rate constant for the uncatalyzed reaction? What is enhancement rate with enzyme?

Answers

Answer: Equilibrium constant without enzyme: 1.46

Reverse rate constant for the uncatalyzed reaction: 2.57 x 10^-4

Enhancement rate with enzyme: 2.47 x 10^3

The reaction, X <-----> Z, has forward rate constants of 4.7 x 10^5/s with enzyme and 1.9 x 10^2/s without enzyme. The reverse rate constant is 1.3 x 10^2/s with enzyme.

Therefore, the equilibrium constant without enzyme, reverse rate constant for the uncatalyzed reaction, and the enhancement rate with enzyme is to be determined.

Concept: A chemical reaction is said to be at equilibrium if the concentration of the reactants and products remains constant with time. At equilibrium, the forward and reverse reaction rates become equal.

The equilibrium constant Kc is given by Kc = [Z] / [X]where, [X] and [Z] are the concentrations of the reactants X and product Z, respectively.

If the rate constant for the forward reaction is kf and the rate constant for the reverse reaction is kr, then the equilibrium constant Kc can also be expressed askf / kr

At equilibrium, kf[X] = kr[Z]

The enhancement rate with enzyme is given by kf(enzyme) / kf(uncatalyzed) = 4.7 x 10^5 / 1.9 x 10^2

= 2.47 x 10^3

The reverse rate constant for the uncatalyzed reaction is

kr(uncatalyzed) = kf(uncatalyzed) / Kc(uncatalyzed)

where, Kc(uncatalyzed) is the equilibrium constant in the absence of enzyme.

The equilibrium constant with enzyme

Kc(enzyme) = kf(enzyme) / kr(enzyme)

= 4.7 x 10^5 / 1.3 x 10^2

= 3.62 x 10^3

The equilibrium constant without enzyme

Kc(uncatalyzed) = Kc(enzyme) / enhancement rate

Kc(uncatalyzed) = 3.62 x 10^3 / 2.47 x 10^3 = 1.46

Thus, the equilibrium constant without enzyme is 1.46.

The reverse rate constant for the uncatalyzed reaction is 2.57 x 10^-4.

The enhancement rate with enzyme is 2.47 x 10^3.

Answer: Equilibrium constant without enzyme: 1.46

Calculation using scientific notation requires the knowledge of how to convert and operate the powers of 10. It is a very useful method to solve calculations with extremely small or large values.

Let's calculate the given expressions. 7.60 × 10^−5 × 1.00 × 10^−8 = (7.60 × 1.00) × (10^−5 × 10^−8)

= 7.60 × 10−13.

Next, 9.97 × 10^4 ÷ 6.05 × 10^2 = (9.97 ÷ 6.05) × (10^4 ÷ 10^2)

= 1.65 × 10^2.

Now, (1.00 × 10^−8) × (5.09 × 10^−4) ÷ (7.60 × 10^−5) ÷ (3.35 × 10^−4) = [(1.00 × 5.09) ÷ (7.60 × 3.35)] × (10^−8 ÷ 10^−5 ÷ 10^−4) = 0.409.  

The calculation method of the given expression is as follows:Firstly, for the first calculation, we should multiply the two numbers and then add the exponents. (7.60×10^−5)(1.00×10^−8) = 7.60 × 1.00 × 10−5+−8

= 7.60 × 10−13.

Secondly, for the second calculation, we should divide the numbers and subtract the exponents. (9.97×10^4) / (6.05×10^2) = (9.97/6.05) × 10^4−2

= 1.65 × 10^2.

For the third calculation, we must divide the numbers and then subtract the denominators' exponents from the numerator's exponent.

Here, R is the gas constant, T is the temperature in Kelvin and K is the equilibrium constant. The standard free energy change (ΔG∘) of a chemical reaction is calculated by using the formula ΔG∘ = −RT ln K.

The equilibrium constant K is given by:K = [C][D]/[A][B]The concentrations of A, B, C, and D are given. So, substituting these values in the above equation we get:K = (2.0 x 1.0)/(5.0 x 0.50)K = 0.80Hence, the equilibrium constant for the given reaction is 0.80.

Assume that methanol thermal decomposition utilizes energy from electricity (S33/01).

*Please don't copy the answer else give a downvote

Answers

The price of energy (S/GI) obtained from burning hydrogen produced from methanol thermal decomposition is S56.50/mLmol.

The reaction given is

CH₃OH → CO + 2H₂,

which represents the thermal decomposition of methanol to produce hydrogen gas. The molar mass of methanol (CH₃OH) is 32.04 g/mol, and its density is 0.791 g/mL at 20°C.

Methanol has a price of S 38/mL. The heat of formation of methanol is -238.7 kJ/mol, and the standard heat of formation of CO is -110.5 kJ/mol, while the standard heat of formation of H₂ is 0 kJ/mol.

The price of energy (S/GI) produced by the combustion of hydrogen obtained from methanol thermal decomposition can be calculated using the following steps:

Step 1: Calculation of moles of hydrogen produced from methanol decomposition. CH₃OH → CO + 2H₂

Step 2: Calculation of the mass of hydrogen produced. The molar mass of hydrogen is 2.016 g/mol.

The mass of hydrogen produced from one mole of methanol = 2 x 2.016 = 4.032 g/mol

Step 3: Calculation of the cost of methanol per mole. The cost of methanol per milliliter = S38/mL

The density of methanol at 20°C = 0.791 g/mL

The volume of one mole of methanol

= 32.04 g/mol ÷ 0.791 g/mL

= 40.518 mL/mol

The cost of one mole of methanol

= 40.518 mL/mol x S38/mL

= S1,539.08/mol

Step 4: Calculation of the cost of hydrogen per mole. The mass of hydrogen produced from one mole of methanol = 4.032 g/mol

The cost of methanol per mole = S1,539.08/mol

The cost of hydrogen per mole

= (4.032 g/mol ÷ 32.04 g/mol) x S1,539.08/mol

= S193.25/mol

Step 5: Calculation of the price of energy produced. The combustion of hydrogen produces water, which has a specific heat capacity of 4.184 J/gK.

Q = mcΔT

Where Q is the heat energy produced, m is the mass of water heated, c is the specific heat capacity of water, and ΔT is the temperature change.

The mass of water that can be heated by the energy produced from one mole of hydrogen can be calculated as follows:

Mass of water heated = Energy produced ÷ (Specific heat capacity of water x Temperature change)

Assuming a temperature change of 20°C,

Mass of water heated = 286 kJ/mol ÷ (4.184 J/gK x 20°C)

= 3.42 g/mol

The price of energy produced from one mole of hydrogen can be calculated as follows:

Price of energy produced

= Cost of hydrogen per mole ÷ (Mass of water heated x Density of water x 1000)

Price of energy produced

= S193.25/mol ÷ (3.42 g/mol x 1 mL/1 g x 1000)

= S56.50/mLmol

The price of energy (S/GI) obtained from burning hydrogen produced from methanol thermal decomposition is S56.50/mLmol.

what are the intermolecular forces of oxalic acid? please include illustration(s).

Answers

Oxalic acid (chemical formula: C2H2O4) is a dicarboxylic acid with two carboxyl groups (-COOH).

The intermolecular forces present in oxalic acid are hydrogen bonding and dipole-dipole interactions.

Hydrogen Bonding:

Oxalic acid contains hydrogen atoms bonded to highly electronegative oxygen atoms.

These hydrogen atoms can form hydrogen bonds with the lone pairs of electrons on neighboring oxygen atoms.

The following illustration shows the hydrogen bonding interactions in oxalic acid:

O     H        O

Dipole-Dipole Interactions:

In addition to hydrogen bonding, oxalic acid also exhibits dipole-dipole interactions.

The presence of the two carboxyl groups creates a polar molecule, where the oxygen atoms are more electronegative than the carbon and hydrogen atoms.

This polarity leads to dipole-dipole interactions between the positive end of one molecule and the negative end of another molecule.

It's important to note that oxalic acid is a solid at room temperature, and in the solid state, intermolecular forces such as hydrogen bonding and dipole-dipole interactions contribute to the stability of the crystal lattice.

Answer:

is the catalytic steam - hydrocarbons process

Heat generated from an exothermic reaction produces an off-gas at 450oC. The hot off-gas is used to raise superheated steam at 300oC from saturated steam at 20 bar in order to recover the heat and conserve energy. Assuming the hot gas flows through the external side of the bank of steam tubes and leaves the superheater at 350oC, and the steam flow rate is 95000 kg/h, calculate the total surface area required for heat transfer.
Given: Heat transfer coefficient on hot gas side = 350 W/(m2K)
Heat transfer coefficient on steam side = 280 W/(m2K)
Thermal conductivity of low-alloy steel pipe = 34 W/(m.K)
Fouling resistance on the hot gas side = 8.81x10-4 m2.K/W
Fouling resistance on the steam side = 8.81x10-5 m2.K/W
Tube thickness = 0.154 inches
Tube inner diameter = 2 inches
Average specific heat capacity of steam = 1.858 kJ/(kg K)

Answers

To calculate the total surface area required for heat transfer, we need to consider the heat transfer on both the hot gas side and the steam side. Let's break down the steps to calculate the surface area:

Determine the heat transfer rate:

The heat transfer rate (Q) can be calculated using the formula:

Q = m_ dot * (h_ steam - h_ gas)

where m_ dot is the steam flow rate (in kg/h) and h_ steam and h_ gas are the specific enthalpies of the steam and hot gas, respectively.

First, we need to calculate the specific enthalpies:

h_ steam = C p_ steam * (T_s team - T_ sat)

h_ gas = C p_ gas * (T_ gas - T_ ref)

where C p_ steam is the average specific heat capacity of steam (in kJ/(kg K)), T_ steam is the steam temperature (in °C), T_ sat is the saturation temperature of steam (in °C), C p_ gas is the specific heat capacity of the hot gas (in kJ/(kg K)), T_ gas is the hot gas temperature (in °C), and T_ ref is the reference temperature (in °C).

Calculate the heat transfer area:

The heat transfer area (A) can be calculated using the formula:

Q = U * A * ΔT

where ΔT is the logarithmic mean temperature difference (LMTD) between the hot gas and steam sides.

Now let's substitute the given values and calculate the total surface area required for heat transfer.

Tube thickness (δ) = 0.154 inches

Tube inner diameter (D) = 2 inches

Average specific heat capacity of steam (C p_ steam) = 1.858 kJ/(kg K)

Heat transfer coefficient on the hot gas side (hi) = 350 W/(m²K)

Heat transfer coefficient on the steam side (h o) = 280 W/(m²K)

Fouling resistance on the hot gas side  = 8.81x10^-4 m²K/W

Fouling resistance on the steam side  = 8.81x10^-5 m²K/W

Calculate the overall heat transfer coefficient (U):

Calculate the inside and outside heat transfer coefficients:

hi = 1/hi

h o = 1/h o

Calculate the overall heat transfer coefficient:

(i) The value of ΔG at standard conditions (-3.4 kJ/mol) and ΔG which is close to zero indicate that the forward and backward reactions have a similar rate, thus this reaction is said to be exothermic.(ii)  For a reaction to be spontaneous, ΔG has to be negative.

Therefore, the following equation will be used to determine the temperature: ΔG = ΔH - TΔSwhere

ΔG = -RTln,

ΔH = enthalpy change,

T = temperature in Kelvin,

ΔS = entropy change, and

K = equilibrium constant. Rewriting the above equation gives;ln

K = (-ΔH/R)(1/T) + ΔS/RTaking the derivative of the right-hand side of the above equation with respect to T gives;1/

T = (ΔH/R)T²The above equation shows that the reciprocal of the absolute temperature is proportional to the square of the equilibrium constant. T

therefore;ln(K2/K1) = (ΔH/R)((1/T1) - (1/T2))ln(K2/1.29 × 10^-2)

= (-ΔH/R)((1/310.15) - (1/T2))Solving for T2 gives;

T2 = (ΔH/R)((1/310.15) - (ln(K2/1.29 × 10^-2))/T)

= (0.068/8.314)((1/310.15) - (ln(4.7))/T)where ΔH = 68 J/mol is obtained from

ΔG = ΔH - TΔS. Setting ΔG to zero, we obtain the equilibrium temperature of this reaction to be 43°C. Thus, above this temperature, the reaction will be spontaneous.

Corn liquor contains 3% invert sugars and 50% water, the rest can be considered solids. Beet molasses contains 50% sucrose, 1% invert sugars, and 18% water; the remainder is solids. A mixing tank contains 125 kg corn liquor and 45 kg beet molasses; water is then added to produce a diluted sugar mixture containing 2% (w/w) invert sugars.
(a) How much water is required?
(b) What is the concentration of sucrose in the final mixture?

Answers

The concentration of sucrose in the final mixture is about 12.97%.

(a) Calculation of the water required to produce a diluted sugar mixture containing 2% (w/w) invert sugars.

Weight of corn liquor = 125 kg

Weight of beet molasses = 45 kg

Total weight of solids = 125 + 45 = 170 kg

Let's consider 'W' kg of water required to produce a diluted sugar mixture containing 2% (w/w) invert sugars

So, invert sugar required to be added to make the diluted sugar mixture= 0.02 × (125 + 45 + W)

= 2.5 + 0.9 + 0.03 '

= 3.43 kg

In corn liquor 3% of invert sugar is present.

So, invert sugar in 125 kg of corn liquor = 3/100 × 125

= 3.75 kg

In beet molasses 1% of invert sugar and 50% of sucrose is present.

So, invert sugar in 45 kg of beet molasses = 1/100 × 45

= 0.45 kg

Sucrose in 45 kg of beet molasses = 50/100 × 45

= 22.5 kg

As the total weight of solids is equal to 170 - W kg (solids = corn liquor + beet molasses), invert sugar is 3.43 - (3.75 + 0.45) = -0.77 kg

Therefore, we need to adjust the water content by this much quantity.

So, the total weight of the mixture = 125 + 45 + W - 0.77 = 169.23 kg

Total amount of water required = 169.23 × 2% = 3.38 kg

= 3.38 liters (since 1 kg of water = 1 liter)

(b) Calculation of the concentration of sucrose in the final mixture.

The weight of the final mixture = 125 + 45 + 3.38

= 173.38 kg

The amount of sucrose in the final mixture = 22.5 kg%

concentration of sucrose in the final mixture = (22.5 / 173.38) × 100%≈ 12.97%

Therefore, the concentration of sucrose in the final mixture is about 12.97%.

To compound a suspension containing 145mg of API, how many grams of capsule powder must be weighed? 4. How many capsules would need to be opened to compound this suspension?

Answers

To compound a suspension containing 145mg of active drug (API) from fluoxetine capsules, we need to determine how many grams of capsule powder must be weighed and how many capsules need to be opened.

1. To find out how many grams of capsule powder must be weighed, we can use a proportion. We know that the average weight of the contents of a fluoxetine 20mg capsule is 248mg. Let's set up the proportion:20mg (API) / 248mg (capsule powder) = 145mg (API) / x (capsule powder)

2. To determine how many capsules need to be opened, we can divide the total weight of capsule powder needed (1796mg) by the average weight of the contents of a fluoxetine 20mg capsule (248mg):

1796mg / 248mg ≈ 7.25

Since we can't have a fraction of a capsule, we need to round up to the nearest whole number. Therefore, we would need to open 8 capsules to compound the suspension.

Persons with a college education are about 40 percent more likely to vote than are persons with a grade school education. Education generates an interest in politics, confidence that one can make a difference politically, and peer pressure to participate-all of these are related to the tendency to vote. Education, in fact, is the single best predictor of voter turnout. Source: Thomas E. Patterson, We the People, 6th ed., p. 238. Copyright O 2006 McGraw-Hill.

Two carts selling coconut milk (from the coconut) are located at 0 and 1, 1 mile apart on the beach in Rio de Janeiro. (They are the only two coconut EXERCISES 153 milk carts on the beach.) The cartsCart 0 and Cart I-charge prices p, and Pu, respectively, for each coconut. Their customers are the beach goers uni- formly distributed along the beach between 0 and 1. Each beach goer will purchase one coconut milk in the course of her day at the beach and, in ad- dition to the price, each will incur a transport cost of 0.5 times d, where dis the distance (in miles) from her beach blanket to the coconut cart. In this system, Cart 0 sells to all of the beach goers located between 0 and x, and Cart 1 sells to all of the beach goers located between x and 1, where x is the location of the beach goer who pays the same total price if she goes to 0 or 1.
