Calculate the strength of 30 volume solution of hydrogen peroxide.

Explanation

To calculate the strength of a 30 volume solution of hydrogen peroxide (H2O2), we can follow these steps:

### Step 1: Understand Volume Strength
Volume strength indicates the volume of oxygen gas (O2) that can be liberated by the decomposition of a certain volume of hydrogen peroxide. A 30 volume solution means that 1 liter of this solution can release 30 liters of oxygen gas.

### Step 2: Write the Decomposition Reaction
The decomposition of hydrogen peroxide can be represented by the following balanced chemical equation:
\[ 2 \text{H}_2\text{O}_2 \rightarrow 2 \text{H}_2\text{O} + \text{O}_2 \]
