Question: The vapour density of a gas is 11.2. The volume occupied by 11.2 g of the gas at ATP will be [Bihar CET 1995]

Options:

A) 11.2 L

B) 22.4 L

C) 1 L

D) 44.8 L

Show Answer

Answer:

Correct Answer: A

Solution:

Molecular weight =2×V.D =2×11.2=22.4

∵ 22.4gm of gas occupies 22.4L at S.T.P.
∴ 11.2gm of gas occupies 22.422.4×11.2=11.2L .
