`1.11g CaCl_(2)` is added to water forming `500ml` of solution `20ml` of this solution is taken and diluted `10` folds Find moles of `Cl` ions in `2ml` of diluted solution .

Explanation

To solve the problem step by step, we will follow the process of calculating the moles of chloride ions in the diluted solution.

### Step 1: Calculate the moles of Calcium Chloride (CaCl₂)
1. **Given Data**: Mass of CaCl₂ = 1.11 g
2. **Molar Mass of CaCl₂**:
- Calcium (Ca) = 40 g/mol
- Chlorine (Cl) = 35.5 g/mol (and there are 2 Cl atoms)
- Molar mass of CaCl₂ = 40 + (2 × 35.5) = 40 + 71 = 111 g/mol
