Answer: this is not my own words :)
Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie
One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.
As in relative abundance , one is take reference
So,
One is taken as 1:
Other is subtracted from it:
(1 - 0.6011)(atomic mass of Ga-71)
Equation can be written as:
<span>69.723 = (0.6011)(68.9256) + (1-0.6011)x </span>
<span>(1-0.6011) is the percentage abundance of Ga-71 expressed in percentage: </span>
<span>Solving for x </span>
<span>28.2918 = 0.3989 x </span>
<span>x= 70.9246.......</span>

Explanation:
please kindly see attachment for the step by step solution of the given problem
The volume increases and the final volume is 2.1 L
<h3>Why volume increases?</h3>
The volume of a gas is directly related to the heat and pressure. If temperature increases, volume increases.
If pressure increases, volume decreases
Based on Boyle's law,
The absolute temperature of a gas is directly proportional to the volume of the gas.
As the balloon change increases its temperature, the volume increases
The Boyle's equation is:
V₁T₂ = V₂T₁
Where,
- V is volume
- T is absolute temperature of 1, initial state and 2, final state of the gas.
Replacing :
V₁ = 2.0L
T₂ = 35°C + 273.15 = 308.15K
V₂ = ?
T₁ = 25°C + 273.15 = 298.15 K
2.0L x 308.15 K = V₂ x 298.15 K
2.1 L = V₂
Final volume is 2.1L
Hence, The volume increases and the final volume is 2.1 L
