Answer:
n₂ = 31 mol
Explanation:
Given data:
Initial volume of gas = 6.2 L
Initial number of moles of gas = 19.2 mol
Final number of moles = ?
Final volume of gas = 10.0 L
Solution:
Formula:
V₁/n₁ = V₂/n₂
V₁ = Initial volume
n₁ = Initial number of moles
V₂ = Final volume
n₂ = Final number of mole
Now we will put the values.
6.2 L /19.2 mol = 10.0 L / n₂
n₂ = 10.0 L× 19.2 mol /6.2 L
n₂ = 192 L.mol /6.2 L
n₂ = 31 mol
