Calculate the strength in g `L^(- 1)` and normality of '30 volume' hydrogen peroxide solution.

Explanation

To calculate the strength in grams per liter (g L^(-1)) and normality of a '30 volume' hydrogen peroxide solution, we can follow these steps:

### Step 1: Understand the meaning of '30 volume'
'30 volume' hydrogen peroxide means that 1 liter of this solution will produce 30 liters of oxygen gas (O₂) at standard temperature and pressure (STP).

### Step 2: Write the balanced chemical equation
The decomposition of hydrogen peroxide (H₂O₂) can be represented by the following balanced equation:
\[ 2 \text{H}_2\text{O}_2 \rightarrow 2 \text{H}_2\text{O} + \text{O}_2 \]
