Q. At STP, 5.6 litre of a gas weighs $60 \, g$ . The vapour density of gas is -

NTA AbhyasNTA Abhyas 2020States of Matter

Solution:

$5.6 \, lit$ gas weight $= \, 60 \, gm$

$22.4 \, lit$ gas weight $= \, \frac{60}{5.6}\times 22.4 \, gm$

$= \, 240 \text{ gm } \left(\right. \text{molecular weight of gas} \left.\right)$

$\text{Vapour density} = \, \frac{\text{M} \text{o} \text{l} \text{e} \text{c} \text{u} \text{l} \text{a} \text{r} \text{ weight}}{2} \, = \, 120$
