0.246 gm of an organic compound gave 0.198 gm of carbon dioxide and 0.1014 gm of water on complete combustion. 0.37 gm of the compound gave 0.638 gm of silver bromide. What is the molecular formula of the compound if its vapour density is `54.4?`

Explanation

To find the molecular formula of the organic compound based on the given data, we can follow these steps:

### Step 1: Calculate the percentage of carbon in the organic compound.
1. **Given:** Mass of organic compound = 0.246 g, Mass of CO₂ produced = 0.198 g.
2. **Molar mass of CO₂ = 44 g/mol**, which contains **12 g of carbon**.
3. **Calculate the mass of carbon in 0.198 g of CO₂:**
\[
\text{Mass of carbon} = \left(\frac{12}{44}\right) \times 0.198 = 0.0540 \text{ g}
