The vapour density of a gas is 11.2. The volume occupied by 11.2 g of this gas at N.T.P. is

A
1 L
B
11.2 L
C
22.4 L
D
20 L

Solution:

Molecular weight= V.d. x 2 = 11.2 x 2 = 22.4 Volume of 22.4 gm Substance of NTP = 22.4 litre

1 gm substance at NTP $= \frac{22.4}{22.4} litre$

11.2 gm substance of NTP = 11.2 litre
