An organic compound with vapour density = 94 contains
C=12.67%, H = 2.13%, and Br = 85-11%. Find the molecular formula.
[Atomic mass: C = 12, H = 1, Br = 80]

Explanation

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

### Step 1: Determine the empirical formula
1. **List the percentages of each element**:
- Carbon (C) = 12.67%
- Hydrogen (H) = 2.13%
- Bromine (Br) = 85.11%
