50 `mL` of ozone \(`O_3`) at STP were passed through 50 `mL` of `5` volume `H_2O_2` solution. What is the volume strength of `H_2O_2` after the reaction?

Explanation

To solve the problem, we need to analyze the reactions that occur when ozone (O₃) is passed through hydrogen peroxide (H₂O₂) and determine the resulting volume strength of the hydrogen peroxide solution.

### Step-by-Step Solution:

1. **Identify the Reaction Between Ozone and Hydrogen Peroxide:**
- Ozone (O₃) reacts with hydrogen peroxide (H₂O₂) to produce oxygen (O₂) and water (H₂O). The reactions can be summarized as:
- \( 2 O_3 \rightarrow 3 O_2 \)
- \( 2 H_2O_2 \rightarrow 2 H_2O + O_2 \)
