0.246 g of an organic substance when heated with excess of fuming nitric acid and silver nitrate gave 0.2584 g of silver bromide. Calculate the percentage of bromine in the compound.

Explanation

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

### Step 1: Understand the relationship between silver bromide (AgBr) and bromine (Br)
When the organic compound containing bromine is treated with fuming nitric acid and silver nitrate, silver bromide (AgBr) is formed. The mass of AgBr formed can be used to determine the amount of bromine in the original compound.

### Step 2: Calculate the moles of silver bromide (AgBr)
To find the moles of AgBr, we use the formula:
\[
