Question

127 $m l$ of a certain gas diffuses in the same time as 100 $m l$ of chlorine under the same conditions, if the molecular weight of the gas is $X$ , then nearest integer value of $X$ is_________.

Solution

As we know,
$\frac{V_{1}}{V_{2}} = \sqrt{\frac{d_{2}}{d_{1}}} = \sqrt{\frac{M_{2}}{M_{1}}}$
$\frac{127}{100} = \sqrt{\frac{71}{M_{1}}}$
$∴ M_{1} = 43.58$
So nearest integer value is 44.
