An organic compound contains C = 16.27%, H = 0.677%, CI = 72.2% and O=10.8%. Its molecular mass is 147.5 amu. Find its molecular formula.

Explanation

To find the molecular formula of the organic compound given its percentage composition and molecular mass, we can follow these steps:

### Step 1: Convert percentages to grams
Assuming we have 100 grams of the compound, the mass of each element can be directly taken as their percentage:
- Carbon (C) = 16.27 g
- Hydrogen (H) = 0.677 g
- Chlorine (Cl) = 72.2 g
- Oxygen (O) = 10.8 g
