Answer: 3 mol of O₂

Solution:

The Balance chemical equation is as follow,

2 KClO₃ → 2 KCl + 3 O₂

According to this equation on decomposition 2 moles of Potassium chlorate (KClO₃) produces 2 moles of Poatassium chloride (KCl) and 3 moles of oxygen gas (O₂).

Therefore, when,

2 moles of KClO₃ produces = 3 moles of O₂

So,

2 moles of KClO₃ will produce = X moles of O₂

Solving for X,

X = (2 mol × 3 mol) ÷ 2 mol

X = 3 mol of O₂

Using above method you can calculate any amount of O₂ or KCl produced by decomposing any amount of KClO₃.
