The volume strength of 1.5 N `H_2 O_2` solution is

Explanation

To find the volume strength of a 1.5 N (Normal) solution of hydrogen peroxide (H₂O₂), we can follow these steps:

### Step 1: Calculate the mass of H₂O₂ in the solution
The normality (N) of a solution is defined as the number of equivalents of solute per liter of solution. For hydrogen peroxide, the equivalent weight is half of its molecular weight because it can release one mole of oxygen (O₂) per mole of H₂O₂ during decomposition.

1. **Molecular weight of H₂O₂**:
- H: 1 g/mol × 2 = 2 g/mol
- O: 16 g/mol × 2 = 32 g/mol
