A balanced equation for the reaction is 3 Mg + 3/2 O2 = 3 MgO. the Atomic Mass of mass of magnesium is about 24.3 and that of oxygen is about 16.0; therefore the mass of magnesium oxide produced is 3 (24.3 + 16.0) = 120.9 grams. (If the specification of "3 moles" of magnesium is considered to have only one significant digit, this answer should be written instead as 1 X 102 grams.)

Why when magnesium ribbon is burnt the ash is heavier?
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.

What are the molar masses of magnesium and atomic oxygen?
Mass of Oxygen is approximately 16 grams. (15.9994 grams) per mole. Mass of Magnesium is approximately 24.305 grams per mole.
Why does magnesium get heavier when its burned?
What happens when magnesium burns? What do you need for magnesium to burn? Will magnesium burn if you have it in a closed container? No. Why not? It needs air. Why does it need air? There is oxygen in the air. Magnesium needs oxygen to burn. So, when magnesium burns, you start with magnesium and end up with a compound that contains both magnesium and oxygen. Magnesium has an atomic weight of 24. Oxygen has an atomic weight of 16. So if you start out with 24 grams of Magnesium you should end up with 40 grams of Magnesium Oxide.
