An organic compound with vapour density 94 contains C = 12.67%, H = 2.13% and Br = 85.20%. Find the molecular formula. (Atomic mass: C = 12, H = 1, Br = 80)

Explanation

To find the molecular formula of the organic compound, we will follow these steps:

### Step 1: Calculate the moles of each element in the compound.

Given the percentages of each element:
- Carbon (C) = 12.67%
- Hydrogen (H) = 2.13%
- Bromine (Br) = 85.20%
