Chlloride samples are prepared for analysis by using NaCl, KCl, `NH_4Cl` separately or as mixtures. What minimum volume of a `5.0%` by weight `AgNO_3` Solution (Density`=1.02`) must be added to a sample wehging 0.321 g in order to ensure complete precipitation of choride in every possible cases?

Explanation

To solve the problem, we need to determine the minimum volume of a 5.0% by weight AgNO₃ solution required to completely precipitate chloride ions from a sample weighing 0.321 g.

### Step-by-Step Solution:

1. **Determine the amount of chloride ions in the sample:**
- The sample can contain NaCl, KCl, or NH₄Cl. We will calculate the maximum possible amount of chloride ions from each of these salts.
- The molar mass of NaCl = 58.44 g/mol, KCl = 74.55 g/mol, and NH₄Cl = 53.5 g/mol.
