B. 32.07 g
C. 64.14 g
D. 160.35 g
Answer:
I guess your answer would be A even thought it is not actually correct it is the closest to being correct.
Explanation:
The molar mass of Al2(SO4)3 is 342.15 g/mol. This means that 1 mole of Al2(SO4)3 has a mass of 342.15 g.To find the mass of sulfur in 2.0 moles of Al2(SO4)3, we first need to determine the number of moles of sulfur in 1 mole of Al2(SO4)3. There are 3 moles of sulfur in 1 mole of Al2(SO4)3, so there are 6 moles of sulfur in 2 moles of Al2(SO4)3.To find the mass of sulfur in 2.0 moles of Al2(SO4)3, we can use the following calculation:Mass of sulfur = (moles of sulfur) x (molar mass of sulfur)
Mass of sulfur = 6 mol x 32.06 g/mol
Mass of sulfur = 192.36 gTherefore, the mass of sulfur in 2.0 moles of Al2(SO4)3 is 192.36 grams.
Calculate the volume of oxygen that will be spent on burning 300 liters of ethane containing 5.8% non-combustible impurities
Answer:
To calculate the volume of oxygen that will be required to burn 300 liters of ethane containing 5.8% non-combustible impurities, we need to determine the amount of pure ethane present.
Since the ethane contains 5.8% non-combustible impurities, 100 - 5.8 = 94.2% of the 300 liters of ethane is pure and can be burned.
The amount of pure ethane is 94.2% * 300 liters = 282.6 liters.
The stoichiometric equation for the complete combustion of ethane is:
C2H6 + 7O2 -> 4H2O + 6CO2
This equation tells us that for every molecule of ethane that is burned, 7 molecules of oxygen are required.
The volume of oxygen required for burning 282.6 liters of ethane is 282.6 liters * 7 = 1989.2 liters.
So, the volume of oxygen that will be required to burn 300 liters of ethane containing 5.8% non-combustible impurities is 1989.2 liters.
Assuming that the non-combustible impurities have no effect on the combustion of ethane, we can calculate the volume of oxygen required to burn 300 liters of ethane as follows:
Write the balanced chemical equation for the combustion of ethane:
C2H6 + 3.5 O2 -> 2 CO2 + 3 H2O
Determine the stoichiometry of the reaction, which tells us the molar ratio of ethane to oxygen required for complete combustion. From the balanced equation, we see that 1 mole of ethane reacts with 3.5 moles of oxygen.
Convert the volume of ethane from liters to moles, using the ideal gas law:PV = nRT
where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas, R is the gas constant, and T is the temperature of the gas. Assuming standard temperature and pressure (STP), which is 1 atm and 0°C, we have:
n = PV/RT = (1 atm * 300 L)/(0.08206 Latm/molK * 273 K) = 12.5 moles of ethane
Calculate the amount of oxygen required for combustion, using the stoichiometry of the reaction:3.5 moles of O2 are required for 1 mole of ethane, so for 12.5 moles of ethane, we need:
12.5 moles of ethane * 3.5 moles of O2/mole of ethane = 43.75 moles of O2
Convert the moles of oxygen to volume, again using the ideal gas law:V = nRT/P = (43.75 mol * 0.08206 Latm/molK * 273 K)/1 atm = 994.8 L of O2
Therefore, approximately 994.8 liters of oxygen will be spent on burning 300 liters of ethane containing 5.8% non-combustible impurities.

There are 1.81 × 10²⁴ molecules of sucrose in the given sample.
How many molecules of sucrose are in the sample?
To calculate the number of molecules of sucrose in the given sample, we need to first determine the number of moles of carbon atoms present in the sample, and then use the molecular formula of sucrose to calculate the number of molecules.
Calculate the number of moles of carbon atoms in the sample:
We know that the sample contains 3.6 × 10²⁴ atoms of carbon. The molar mass of carbon is approximately 12 g/mol.
Therefore, the mass of carbon in the sample can be calculated as follows:
mass of carbon = number of atoms of carbon × molar mass of carbon
= 3.6 × 10²⁴ × 12 g/mol
= 4.32 × 10²⁵ g
To calculate the number of moles of carbon in the sample, we divide the mass of carbon by the molar mass of carbon:
number of moles of carbon = mass of carbon / molar mass of carbon
= 4.32 × 10²⁵ g / 12 g/mol
= 3.6 × 10²⁴ mol
Calculate the number of molecules of sucrose in the sample:
To calculate the number of molecules of sucrose in the sample, we can use the following formula:
number of molecules of sucrose = (number of moles of carbon / 12) × Avogadro's number
where;
Avogadro's number is approximately 6.02 × 10²³ molecules/mol.Substituting the values, we get:
number of molecules of sucrose = (3.6 × 10²⁴ mol / 12) × 6.02 × 10²³ molecules/mol

Answer:
The molecular weight of glucose (C6H12O6) is 6(12.01) + 12(1.01) + 6(16.00) = 180.18 g/mol.
So, the number of moles of glucose present in 240.0 g can be calculated as follows:
n = m/M = 240.0 g / 180.18 g/mol = 1.33 mol
And the number of molecules of glucose can be calculated as follows:
N = n x Avogadro's constant = 1.33 mol x 6.022 x 10^23 molecules/mol = 7.98 x 10^23 molecules
Therefore, the number of molecules of glucose present in 240.0 g is 7.98 x 10^23 molecules, rounded to the nearest whole number.
So, the coefficient is 7.98 and the exponent is 23.

If a reaction is first order with a rate constant of 0.0450 s⁻¹, 23.3 sec is the time that is required for 65% of the initial quantity of reactant to be consumed.
A first-order reaction in chemistry is a particular kind of chemical process where the rate of the reaction is exactly related to the concentration of just one ingredient. With respect to that specific reactant, the reaction rate is referred to as first-order.
First order rate law is given by,
A = A0 × [tex]\rm e^{-kt}[/tex]
A0 = Initial concentration=100 M
A = Final concentration=35 M (65% is consumed means 35% is the remaining compound)
K = Rate constant = 0.0450 [tex]\rm s^{-1}[/tex]
Substituting,

Which mass of Carbon id produced?
Answer:
(c) 4.4g
Explanation:
Given:
mass of calcium carbonate (mCaCO3) = 10g
MrCaCO3 = 100
To find: mCO2
Solution:
CaCO3 + 2HCl → CaCl 2 + H2O + CO2
Now,
MrCaCO3 = 40 + 12 + 16.3 = 100
Therefore,
Number of moles (n) = m/Mr
nCaCO3 = 10/100 = 0.1
The amount of moles is proportional to the coefficient of the reaction. Since both calcium carbonate (CaCO3) and carbon dioxide (CO2) have the same coefficient.
nCO2 = 0.1
MrCO2 = 12 + 16.2 = 44
mCO2 = 0.1 × 44 = 4.4g
1. A pupil dissolved 180.00 grams of C6H1206 in 1,000.0 grams of
water and then heated the solution until it boiled. What was the
boiling point of the C6H12O6 solution? (air pressure is 1
atmosphere) (1) 98.96°C (2) 100.52°C (3) 99.48°C (4) 101.04°C
The boiling point of a solution depends on the concentration of solute in the solution. When a solute is dissolved in a solvent, it raises the boiling point of the solution compared to the boiling point of the pure solvent. This is because the solute particles interfere with the hydrogen bonding between the solvent molecules, making it more difficult for the solvent to evaporate.
In this case, 180.00 grams of C6H12O6 (glucose) has been dissolved in 1,000.0 grams of water, so the concentration of glucose in the solution is 180.00 g / 1000.0 g = 0.18 g/g, or 18%.
The boiling point of a solution can be estimated using the formula ΔTb = Kb x molality, where ΔTb is the change in boiling point, Kb is the molal boiling point constant for water (0.512 °C/m), and molality is the concentration of solute in the solution in moles per kilogram of solvent.
Using this formula, the change in boiling point for the glucose solution can be calculated as follows:
ΔTb = Kb x molality = 0.512 °C/m x (0.18 moles/kg) = 0.093 °C
The boiling point of pure water at 1 atmosphere is 100.0 °C, so the boiling point of the glucose solution is 100.0 °C + 0.093 °C = 100.093 °C.
Therefore, the answer to the question is (3) 99.48°C.
What is the boiling point, in °C, of a 0.527 m aqueous solution of LiBr?
BP(water) = 100 °C
Kb (water) = 0.512 °C/m [ ? ] °C
To solve this we must know the concept behind the phenomenon of elevation in boiling point when a non volatile solute is added to any solvent. Therefore, boiling point in °C of a 0.527 m aqueous solution of LiBr is 100.54 °C.
Mathematically,
ΔT= Kb× molality
The complete balanced equation can be written as
LiBr → Li⁺ + Br⁻ [two ions]
substituting all the given values in the above mathematical expression, we get
(0.527 m LiBr) x (2 mol ions / 1 mol LiBr) = 1.054 m ions
(0.512 °C/m) x (1.054 m) = 0.540 °C change
100.00°C + 0.540 °C = 100.54 °C
Therefore, the boiling point in °C of a 0.527 m aqueous solution of LiBr is 100.54 °C.

Entropy is the measure of randomness in a macroscopic system. It is equal with the ratio of heat absorbed in Joules (Q) and the temperature at which the heat is absorbed in Kelvin (T). If one wants the entropy to decrease, they must transfer the energy from outside the system.

how do milk, corn syrup, and pineapple juice react in the benedict’s reagent? why?
Milk, corn syrup, and pineapple juice all react with Benedict's reagent to produce a color change, indicating the presence of reducing sugars.
This is because Benedict's reagent contains copper ions that are reduced by the aldehyde or ketone groups of the reducing sugars, forming a brick-red precipitate of copper(I) oxide.
Milk and corn syrup contains lactose and glucose/fructose, respectively, while pineapple juice contains primarily sucrose. All of these sugars have reducing properties that react with the copper ions in Benedict's reagent. The intensity of the color change can be used to estimate the concentration of reducing sugars in a sample.
