Answer: B) 3.8 liters
Explanation: Using the Avogadro's Law states which states that the volume of a gas is directly proportional to the number of moles of gas.
Represented as
V ∝ n
(V₁/V₂) = (n₁/n₂)
V is volume of gas
n is number of moles
So the data we were given;
V₁ = 2.5
V₂ = X
n₁ = 0.30
n₂ = 0.30 + 0.15 = 0.45
(V₁/V₂) = (n₁/n₂)
V₁n₂ = V₂n₁
V₂ = V₁n₂ / n₁
We input our numbers
V₂= (2.5 × 0.45) / 0.30
V₂ = 1.125 / 0.30
V₂ = 3.75 approximately 3.8 litres
Therefore final volume of the gas will be 3.8 litres
