There are three samples of `H_(2)O_(2)` labelled as `10 vol,15 vol,20 vol`. Half liter of each sample are mixed and then diluted with equal volume of water. Calculate the volume strength of resultant solution.

Explanation

To solve the problem of calculating the volume strength of the resultant solution after mixing three samples of hydrogen peroxide (H₂O₂) labeled as 10 vol, 15 vol, and 20 vol, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Volume Strength Concept**:
- The volume strength of hydrogen peroxide (H₂O₂) is defined as the volume of oxygen (O₂) released at standard temperature and pressure (STP) by one volume of the solution. The relationship between volume strength and normality is given by:
\[
\text{Volume Strength} = 5.6 \times \text{Normality}
