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`=1.04`) must be added to a sample wehging 0.3 g in order to ensure complete precipitation of choride in every possible cases?

Explanation

To solve the problem of determining the minimum volume of a 5.0% by weight AgNO₃ solution required to ensure complete precipitation of chloride ions from a 0.3 g sample, we will follow these steps:

### Step 1: Determine the amount of chloride in the sample
Given that the sample can contain NaCl, KCl, or NH₄Cl, we first need to calculate the maximum amount of chloride that could be present in the 0.3 g sample.

- **NaCl**: Contains 1 mole of Cl⁻ per mole of NaCl.
- **KCl**: Contains 1 mole of Cl⁻ per mole of KCl.
- **NH₄Cl**: Contains 1 mole of Cl⁻ per mole of NH₄Cl.
