Magnesium in the amount of a substance of 1.5 mol was burned in oxygen. Determine the mass of the resulting magnesium oxide.

The combustion reaction of magnesium is described by the following chemical reaction equation:

Mg + 0.5 O2 = MgO;

From one mole of magnesium, one mole of magnesium oxide is formed. This consumes 0.5 mol of oxygen.

Determine the mass of 1.5 mol of magnesium oxide.

M MgO = 24 + 16 = 40 grams / mol;

m MgO = 1.5 x 40 = 60 grams;
