Question

The vapour density of a gas is $11.2$. The volume occupied by $11.2g$ of the gas at S.T.P. is

• A. 11.2 lit
• B. 4 lit
• C. 2 lit
• D. 22.4 lit

Answer 1

The correct option is A

11.2 lit

$M.W=2\times VD$

= $2\times 11.2=22.4g$

$22.4g$ occupy $22.4L$

$\therefore 11.2g$ occupy $11.2L$
