The combustion reaction of magnesium is described by the following chemical reaction equation:
2Mg + O2 = 2MgO;
To obtain one mole of magnesium oxide, one mole of magnesium is required.
Let us determine the mass of 0.3 mol of magnesium oxide.
The molar mass of magnesium oxide is:
M MgO = 24 + 16 = 40 grams / mol;
m MgO = 40 x 0.3 = 12 grams;
