Step 1: Understand the Carius Method for Halogens

In the Carius method, the organic compound is heated with fuming nitric acid in a sealed tube (Carius tube). Halogen is quantitatively converted to its silver halide:

Step 2: Determine Molar Masses

- Molar mass of AgCl = 107.87 + 35.5 = 143.5 g/mol (using Ag ≈ 108 g/mol)
- Molar mass of Cl = 35.5 g/mol

Step 3: Calculate Mass of Chlorine in 141 mg AgCl

Since each mole of AgCl contains one mole of Cl:

Step 4: Calculate Percentage of Chlori
