The Mg was burned in air. We assumed it mixed solely with oxygen, but that is not entirely correct. At high temperatures, Mg will also combine with nitrogen in air to form magnesium nitride. Suppose some of your product was magnesium nitride instead of MgO. How would this impact the mass of the product obtained, the calculated mass of oxygen used, and the ratio of Mg to O?
