0.15 gm of an organic compound gave 0.12 gm of silver bromide by the carius method. Find the percentage of bromine in the compound.

Explanation

To find the percentage of bromine in the organic compound, we can follow these steps:

### Step 1: Determine the mass of bromine in silver bromide (AgBr)
We know that 0.12 grams of silver bromide (AgBr) was produced. The molar mass of AgBr is calculated as follows:
- Molar mass of Ag = 107.87 g/mol
- Molar mass of Br = 79.90 g/mol
- Therefore, Molar mass of AgBr = 107.87 + 79.90 = 187.77 g/mol (approximately 188 g/mol).
