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, we will follow these steps:

### Step 1: Calculate the number of moles of NaOH
To find the number of moles (N) of NaOH, we use the formula:
\[ N = \frac{\text{mass of solute (g)}}{\text{molar mass of solute (g/mol)}} \]
