Commerical 11.2 volume `H_2 O_2` solution has a molarity of

Explanation

To find the molarity of a commercial 11.2 volume solution of hydrogen peroxide (H₂O₂), we can follow these steps:

### Step 1: Understand the volume concept
The term "11.2 volume" means that 11.2 liters of oxygen gas (O₂) is produced from 1 liter of the H₂O₂ solution when it decomposes.

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