Question

The vapor density of a gas is 16, find its molecular weight.

Answer 1

Given:

Vapor density of the gas$=16$.

Step 1. Relationship between vapor density and molecular weight:

$\text{Molecular weight=2×Vapor density}$

Step 2. Calculation of molecular weight:

$\text{Molecular weight=2×16}=32\mathrm{g}$

Hence, the molecular weight of gas is $\mathbf{32}\mathbf{}\mathbf{g}$.
