Calculate the weight of NaOH present in 500 ml of 0.5 N solution.

Explanation

To calculate the weight of NaOH present in a 500 ml of 0.5 N solution, we can follow these steps:

### Step 1: Understand Normality and Equivalent Weight
Normality (N) is defined as the number of equivalents of solute per liter of solution. For NaOH, which dissociates into Na⁺ and OH⁻, the equivalent weight is the same as its molecular weight since it provides one hydroxide ion (OH⁻) per molecule.

### Step 2: Calculate the Molecular Weight of NaOH
The molecular weight of NaOH can be calculated as follows:
- Sodium (Na) = 23 g/mol
