The reaction is:2 KClO3 = 2 KCl + 3 O238,4 moles of oxygen are produced.


How many moles of potassium chlorate must be used to produce 6 moles of oxygen gas?

2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3


How many moles of oxygen would be produced by 1.2 moles of KClO3?

A balanced equation for the reaction is 2 KClO3 -> 2 KCl + 3 O2. Therefore, each mole of potassium chlorate produces 3/2 moles of oxygen, and 1.2 moles of potassium chlorate produces (3/2)1.2 or 1.8 moles of oxygen.
