Question #52700

How many molecules of oxygen gas, O2, are produced in

2KCIO3 → 2KCI + 3O2

2KCIO3 → 2KCI + 3O2

Expert's answer

Potassium chlorate decompose to form potassium chloride and oxygen, according to the following reaction:

2KClO_{3} = 2KCl + 3O_{2}

It is shown that from 2 mol of potassium chlorate we can obtain 3 mol of oxygen, so from 1 mol of potassium chlorate we will obtain 1.5 mol of oxigen. It is well known fact, that in 1 mole of pure substance there are 6.023·10^{23} molecules, so 1.5 mol of oxigen contain **9.035·10**^{23} molecules of oxygen.
