The molecular weight of a gas is 44. The volume occupied by 2.2 g of this gas at 0⁰C and 2 atm. Pressure will be
Options
(a) 0.56 litre
(b) 1.2 litre
(c) 2.4 litre
(d) 5.6 litre
Correct Answer:
0.56 litre
Explanation:
Number of moles of gas = 2.2 / 44 = (1 / 20) mol
One mole of a gas occupies 22.4 litre at N.T.P.
PV = nRT
P₁V₁ / P₂V₂ = n₁ / n₂ ⇒ V₂ = (P₁ / P₂) × (n₁ / n₂).V₁ = 22.4 / (20 × 2)
V₂ = 0.56 litre
