A solution of `KMnO_(4)` containing `3gL^(-1)` is used to titrate `H_(2)O_(2)` solution containing `2gL^(-1)` What volume of `KMnO_(4)` will be required to react with 20 " mL of " `H_(2)O_(2)`?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Write the balanced chemical equation
The balanced reaction between potassium permanganate (KMnO4) and hydrogen peroxide (H2O2) is as follows:

\[ \text{MnO}_4^- + 5 \text{H}_2\text{O}_2 + 6 \text{H}^+ \rightarrow 2 \text{Mn}^{2+} + 5 \text{O}_2 + 8 \text{H}_2\text{O} \]
