Question

A gas has a vapour density $11.2$. The volume occupied by 1 gm of gas at NTP is:

• A. 1 litre
• B. 11.2 litre
• C. 22.4 litre
• D. unpredictable

Answer 1

Answer: (A)

1 litre

Answer 2

Molecular weight $=2 \times$ vapour density $=2 \times 11.2=22.4$ AT N.T.P. $22.4$ gm gas occupy $22.4$ litre volume $\therefore 1 \,gm$ gas occupy $=\frac{22.4}{22.4} \times 1=1$ litre
