Answer to Question #52700 in Inorganic Chemistry for kayla
2KCIO3 → 2KCI + 3O2
2KClO3 = 2KCl + 3O2
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 6.023·1023 molecules, so 1.5 mol of oxigen contain 9.035·1023 molecules of oxygen.
