Calculate the molar mass of magnesium oxide.

Magnesium oxide is made up of one magnesium atom and one oxygen atom and has the chemical formula MgO.

In order to calculate the molar mass of magnesium oxide, you need to add the molar masses of magnesium and oxygen.

M Mg = 24 grams / mol;

M O = 16 grams / mol;

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