How many grams of magnesium oxide can be produced when 97.2 g Mg react with 88.5 g O2?

Unbalanced equation: Mg + O2 → MgO

To solve this problem, we determine the limiting reactant between magnesium and oxygen. In this case, we convert each to number of moles and divide by corresponding stoich coeff. In this case, Mg has 4.05 while O2 has 2.77. Hence we use the amount of O2. The mass of magnesium oxide is equal to 110.625 grams via stoich
