Aluminium reacts with oxygen to form aluminium oxide.How many grams of potassium chlorate would be heated to produce enough oxygen to form 5.1 grams of aluminium oxide?

Answer 1

4Al + 3O2 = 2Al2O3
2KClO3 --> 2KCl + 3O2

5.1g Al2O3 = 5.1/101.96 = 0.050 moles Al2O3

So, you need 3/2 * 0.050 = 0.075 moles of O2.

Thus, you need 2/3 * 0.075 = 0.050 moles KClO3 to produce that needed O2.
