Empirical Formula of Magnesium Oxide AP Chemistry Stoichiometry Kit

This AP Chemistry kit provides the materials needed to determine the empirical formula of magnesium oxide through a combustion reaction. Students heat magnesium metal in a crucible over a Bunsen burner, measure mass before and after oxidation, and use the data to calculate the mole ratio of magnesium to oxygen. The experiment demonstrates the law of conservation of mass and the law of constant composition. By comparing the mass of magnesium consumed to the mass of oxygen gained, students derive the empirical formula and observe stoichiometric relationships firsthand. Designed for advanced chemistry courses, the kit reinforces skills in mass measurement, mole calculations, and chemical formula determination. A teacher guide with expected data and discussion questions is included.
