If the empirical formula of a compound is CH and its vapour density is 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: Understand the relationship between vapor density and molecular weight
The molecular weight (M) of a gas can be calculated using the formula:
\[ M = 2 \times \text{Vapor Density} \]

### Step 2: Calculate the molecular weight
Given that the vapor density is 13, we can substitute this value into the formula:
...
