If the empirical formula of a compound is CH and it has a vapour density of 13, find the molecular formula of the compound.

Explanation

To find the molecular formula of the compound with an empirical formula of CH and a vapor density of 13, we can follow these steps:

### Step 1: Calculate the Molecular Mass
We know that vapor density (VD) is related to the molecular mass (MM) by the formula:
\[ \text{Vapor Density} = \frac{1}{2} \times \text{Molecular Mass} \]
Given that the vapor density is 13, we can set up the equation:
