An organic compound contains `49.3%` carbon, `6.84%` hydrogen
and `43.86%` of oxygen and its vapour density is 73 . Molecular formula of the compound is

Explanation

To determine the molecular formula of the organic compound with the given percentage composition and vapor density, we can follow these steps:

### Step 1: Calculate the Moles of Each Element
Given the percentages of carbon (C), hydrogen (H), and oxygen (O), we can convert these percentages to moles.

- **Carbon (C)**:
\[
\text{Moles of C} = \frac{49.3 \, \text{g}}{12 \, \text{g/mol}} = 4.1083 \, \text{mol}
