Potassium chloride and oxygen gas are formed upon heating potassium chlorate. The following balanced equation shows this decomposition process:
2KClO3(s) → 2KCl(s) + 3O2(g)
The chemical amount of KClO3 required to produce 5.0 mol of oxygen is:

(5.0 mol O2) x (2 mol KClO3 / 3 mol O2) = 3.3 mol KClO3
(5.0 mol O2) x (2 mol KClO3 / 3 mol O2) x (122.5495 g KClO3/mol) = 400 g KClO3
