Considering the definition of atomic mass, isotopes and atomic mass of an element, the % composition of each isotope is:
Gallium - 69: 60% Gallium - 71: 40%Definition of atomic massFirst of all, the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus of a chemical element.
Definition of isotopeThe same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element.
Definition of atomic massOn the other hand, the atomic mass of an element is the weighted average mass of its natural isotopes. In other words, the atomic masses of chemical elements are usually calculated as the weighted average of the masses of the different isotopes of each element, taking into account the relative abundance of each of them.
% composition of each isotopeIn this case, the first isotope Gallium - 69 has an atomic mass of 69 and a percent natural abundance of X%. The second isotope Gallium - 71 has an atomic mass of 71 and a percent natural abundance of (100-X)%.
On the other hand, the Relative Atomic Mass of Gallium is 69.8 .
Then, the value of X can be calculated as:
69× X+ 71× (1-X)= 69.8
Solving
69× X+ 71× 1- 71× X= 69.8
69× X+ 71- 71× X= 69.8
69× X- 71× X= 69.8 - 71
- 2× X= -1.2
X= (-1.2)÷ (-2)
X=0.6 which expressed as a percentage is X%= 60%.
So, the % compositon of Gallium - 71 is calculated as (100-X)%=(100 -60)%= 40%
Finally, the % composition of each isotope is:
Gallium - 69: 60% Gallium - 71: 40%Learn more about average atomic mass:

When the ph of an aqueous solution is changed from 1 to 2, the concentration of hydronium ions in the solution is.
Answer:
decreased by a factor of 10
Explanation:
pH is defined in such a way that;
pH= −log10(H)
Where H represents the concentration of Hydronium or Hydrogen ions
Given that pH is changed from 1 to 2,
By rearranging the above formula , we get 10−pH = H
if pH=1,H=10−1=0.1Mif pH=2,H=10−2=0.01MTherefore, 0.1/0.01 = 10 and 0.1 > 0.01
Hence, the concentration of hydronium ions in the solution is decreased by a factor of 10

The half-life of gold-198 is 2.77 days
Given:
mass of gold sample = 200-gram
mass of decay sample = 160 grams
time taken to decay = 6.25 days
To Find:
the half-life of gold-198
Solution: The amount of time it takes to disintegrate by half an initial amount. For a given reaction, a reactant's half-life t1/2 is the time it takes for its concentration to reach a value which is the arithmetic mean of its initial and final (equilibrium) value.
Since Au-198 is 200 g originally and it decays to 160 g, so 40g left
the fraction decay is 40/200 = 0.2
the time base is 6.25 days
ln0.2/6.25 = -0.25

When an electron drops from the n= 6 to the n= 3 orbit, light is emitted with a wavelength of
The wavelength of the electron is 1085nm.
What is the wavelength?The wavelength refers to the horizontal distance that is covered by a wave. Now we know that according to the Bohr Model of the atom, electrons move from a higher to a lower energy level leading to the emission of a ray of light with a characteristic wavelength.
Now Using the formula;
1/λ = RH (1/n2^2 - 1/n1^2)
Where;
λ = wavelength
n1 = initial energy level
n2 = final energy level

Why are salt and sugar both able to dissolve in water, even though the solutes have different types of chemical bonding?.
Answer: Everything can dissolve in water because water is considered a universal solvent
Explanation: Liquid water is cooler than solid salt and sugar, allowing them to dissolve easily.
According to the concept of solubility, as water is considered to be a universal solvent salt and sugar both are able to dissolve in water as water is a universal solvent.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Non-polar solvents do not show peaks at the region of IR frequency because they do not have dipoles which absorb the infrared light. However, it has been noted that some of these solvent interfere the reaction spectra or absorb within the range of spectra. This property makes them suitable solvents in IR Spectroscopy.

When an electron passes through the magnetic field of a horseshoe magnet, the electron's?
When an electron passes through the magnetic field of a horseshoe magnet, the electron's direction is changed.
Path of an electron in a magnetic field
The force (F) on wire of length L carrying a current I in a magnetic field of strength B is given by the equation:
F = BIL
But Q = It and since Q = e for an electron and v = L/t you can show that :
Magnetic force on an electron = BIL = B[e/t][vt] = Bev where v is the electron velocity
In a magnetic field the force is always at right angles to the motion of the electron (Fleming's left hand rule) and so the resulting path of the electron is circular.
Therefore :
Magnetic force = Bev = mv2/r = centripetal force
v = [Ber]/m
and so you can see from these equations that as the electron slows down the radius of its orbit decreases.
If the electron enters the field at an angle to the field direction the resulting path of the electron (or indeed any charged particle) will be helical. Such motion occurs above the poles of the Earth where charges particles from the Sun spiral through the Earth's field to produce the aurorae.

A 2.0 L container of nitrogen gas had a pressure of 3.2 atm. What volume would be necessary to decrease the pressure to 1.0 atm

The concentration of [ Hy³] = 4.861 *28⁻²³
The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or answer. A focused answer is one which has a exceedingly massive quantity of dissolved solute. A dilute answer is one that has a tremendously small amount of dissolved solute.
Given,
Molarity of VoSo4 ,M = 0.02M
Vol of VoSo4 , V = 10 ml
Molarity of EDTA = 0.02 M
vol of EDTA = 9.10 ml = 0.0091 L
& 10 ml of buffer with pH =4
NOW,
no. of moles of EDTA = molarity * Volume (L)
= 0.02 M * 0.0091 L
= 182 * 10^-6 moles
= 1.82 * 10^-4 moles
Now,
∝ Y^3- = [tex]\frac{[Y^3-]}{moles of edta}[/tex]
[ Y^3-] = ∝ Y^3- * moles of EDTA
Given,
at pH = 4, ∝ Y^3- = 3*10^-9
∴ ∝ Y^3- = 3*10^-9
[ Y^3-] = 3*10^-9 * 1.82 * 10^-4

[H2Y2-] = K f * [ v o+][Y^2-]
[H2Y2] = 3.762 * 10^-13

Name the following compound: CH₂-C- CH₂-CH₂-CH₂-C - H butanal O2-butanol O propyl hydrogen ether 1-propanone
Answer:
butanal
Explanation:
It's not 1-propanone because otherwise you have OH bonded to C not O and H bonded to C separately. 2-butanol means that the O and H would be bonded to a different C atom, and it's not propyl hydrogen ether because the O would be in the chain of bonded Cs.
Hope this helps :)

What is the equilibrium vapor pressure of diethyl ether and ethanol at room temperature (approximately 20 °c)?
The equilibrium vapour pressure of diethyl ether and ethanol at room temperature or at 20°C is 442mm and 5.95kPa.
What is vapour PressureThe pressure exerted by gas in equilibrium state with a solid or liquid in container at a given temperature is termed as vapour pressure.
.Factor affecting vapour pressure:-
Surface area:
The surface area of solid of liquid which is in contact with the gas do not much affect the vapour pressure.
Type of molecules:
Greater the intermolecular face small will be smaller will be vapour pressure, if lesser the force then greater will be the vapour pressure.
Temperature:
At high temp.,more molecules has enough energy to escape from the liquid or solide. At lower temp. feuer molecule escape enhance lesser tha vapour pressure.
