What volume of water is to be added to 100 `cm^3` of 0.5M NaOH solution to make it 0.1 M solution?

Options

A. `200cm^3`
B. `400cm^3`
C. `500cm^3`
D. `100cm^3`

Explanation

To solve the problem of determining what volume of water needs to be added to 100 cm³ of a 0.5 M NaOH solution to dilute it to a 0.1 M solution, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Information:**
- Initial volume (V1) = 100 cm³
- Initial molarity (M1) = 0.5 M
- Final molarity (M2) = 0.1 M
