Calculate The volume of oxygen at STP obtained by decomposing 12.26 of `KClO_(3)`.

Explanation

To calculate the volume of oxygen at STP obtained by decomposing 12.26 g of KClO₃, we will follow these steps:

### Step 1: Write the balanced chemical equation
The decomposition of potassium chlorate (KClO₃) can be represented by the following balanced equation:

\[ 2 \text{KClO}_3 \rightarrow 2 \text{KCl} + 3 \text{O}_2 \]
