MCQ

At $NTP, 5.6\, litre$ of a gas weight $8\, gram$. The vapour density of gas is :-

A
$32$
B
$40$
✓
$16$
D
$8$

✓

Answer

Correct option: C.

$16$

c
mol of gas $=\frac{\text { mass }}{m 01-\text { mass }}=\frac{V_{s. T. P}}{22.4}$

$\frac{8}{m}=\frac{5.6}{22.4}$

$\therefore $ $\mathrm{m}=32 ; \text { vapour density }=16$
