0.40 g of an organic compound gave 0.30 g of silver bromide by carius method. Determine the percentage bromine in the compound.

Explanation

To determine 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 0.30 g of AgBr was produced. First, we need to find out how much bromine (Br) is present in this amount of AgBr.

The molar mass of AgBr can be calculated as follows:
- Molar mass of Ag (Silver) = 108 g/mol
- Molar mass of Br (Bromine) = 80 g/mol
