The number of moles of the gas sample present at the end is 0.78 moles.
<h3>
Number of moles of the gas</h3>
PV = nRT
V = nRT/P
At a constant volume, V;
n₁RT₁/P₁ = n₂RT₂/P₂
n₁T₁/P₁ = n₂T₂/P₂
n₂ = (n₁T₁P₂)/(P₁T₂)
where;
- T₁ is initial temperature = 21.7⁰C = 294.7 K
- T₂ is final temperature = 28.1⁰C = 301.1 K
n₂ = (3 x 294.7 x 0.998)/(3.75 x 301.1)
n₂ = 0.78 moles
Thus, the number of moles of the gas sample present at the end is 0.78 moles.
