Calculate the molarity of NaOH in the solution prepared by dissolving its 4 g in enough water to form 250 mL of the solution.

Explanation

To calculate the molarity of NaOH in the solution prepared by dissolving 4 g in enough water to form 250 mL of the solution, follow these steps:

### Step-by-Step Solution:

1. **Identify the Formula for Molarity**:
Molarity (M) is defined as the number of moles of solute (n) divided by the volume of the solution in liters (V).
\[
M = \frac{n}{V}
