1

Choose the best answer

At STP (273 K and 1 atm), 11.2 g of a gas has a vapour density of 11.2. What volume does it occupy?

Verified Answer & Explanation⌄

Correct Answer: C) 11.2 L

Concept Explanation

Molar mass = 2 × vapour density = 22.4 g mol⁻¹. Thus 11.2 g = 0.50 mol, which occupies 11.2 L at STP.
