Answer:
The volume of the gas decreases also in a 21% based on the Avogadro's law
Explanation:
Based on Avogadro's law, the volume of a gas is directely proportional to the amount of moles of gas when temperature and pressure remain constants.
The formula is:
V1 / n1 = V2 / n2
Where V is volume and n are moles in 1, initial state and 2, final state of the gas.
At beginning, V1 = 100%, n1 = 100%,
As the chemist removes 21% of the gas, 79% of moles remain = n2.
Replacing:
100% / 100% = V2 / 79%
V2 = 79%, that means:
