Question

The V.D. of a gas is 11.2. The volume occupied by one gm of the gas at STP is: (A) 1.0 litre (B) 11.2 litre (C) 22.4 litre (D) none of these

Tardigrade Admin · Accepted Answer

Here, vapour density of gas =11.2 ∴ Molecular weight =2 × VD =2 × 11.2=22.4 gm 22.4 gm of gas occupied volume at STP =22.4 L ∴ 1 gm gas occupied volume at STP =1 litre

Q. The $V . D .$ of a gas is $11.2$ . The volume occupied by one gm of the gas at STP is:

1.0 litre

11.2 litre

22.4 litre

none of these

Here, vapour density of gas $= 11.2$
$∴$ Molecular weight $= 2 \times V D$
$= 2 \times 11.2 = 22.4 g m$
$22.4 g m$ of gas occupied volume at STP
$= 22.4 L$
$∴ 1 g m$ gas occupied volume at STP
$= 1$ litre
