Choose the best answer

For equal masses of O₂, H₂ and CH₄ at the same temperature and pressure, the volume ratio O₂ : H₂ : CH₄ is:

Verified Answer & Explanation⌄

Correct Answer: B) 1 : 16 : 2

Concept Explanation

For equal masses: V ∝ n ∝ 1/M So: 1/32 : 1/2 : 1/16 Multiplying by 32 gives: 1 : 16 : 2.
