Compute the mass of potassium chlorate `(KClO_(3)) ` that should decompose to produce 8 g of oxygen as per the chemical equation , `2KClO_(3) to 2KCl + 3O_(2)(g)`
(R.A.M : K = 39, Cl = `35.5,O = 16`.)

Explanation

To solve the problem of computing the mass of potassium chlorate (KClO₃) that should decompose to produce 8 g of oxygen (O₂), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chemical Reaction**:
The decomposition of potassium chlorate is given by the equation:
\[
2 \text{KClO}_3 \rightarrow 2 \text{KCl} + 3 \text{O}_2
