Question

The volume occupied by $22.4g$ of a gas ( vap. density $=11.2$) at NTP is:

• A. $22.4$ litres
• B. $11.2$ litres
• C. $44.8$ litres
• D. $1$ litres

Answer 1

The correct option is A $22.4$ litres

We know that,

Molecular mass=2$\times$ vapour density

$=2\times 11.2$

$=22.4gm$

At NTP,

Number of moles $=\frac{22.4}{22.4}=1mole$

Volume occupied by 22.4 g gas $=1\times 22.4$

$=22.4l$

Hence, option A is correct.
