Question

The vapour density of a gas is $8$. Then the volume occupied by $24.0$ g of the gas at STP is _____.

[Please give your answer in the form of nearest integer]

Answer 1

Molecular weight = V.D $\times$ $2=16$

$16$ g of the gas occupies $22.4$ lit. at S.T.P.

Then, $24$g of the occupies = $\frac{24}{16}\times 22.4$ = $33.6$ lit. at STP.

Thus, the volume occupied by the gas is $33.6$lit. at STP.
