Calculate the volume of 0.2N solution required to prepare 200 mL of 0.05 N solution .

Explanation

To solve the problem of calculating the volume of a 0.2N solution required to prepare 200 mL of a 0.05N solution, we can use the concept of dilution and the relationship between normality and volume.

### Step-by-Step Solution:

1. **Identify the known values**:
- Normality of the first solution (N1) = 0.2 N
- Normality of the second solution (N2) = 0.05 N
- Volume of the second solution (V2) = 200 mL
