Mods. Empirical Formula of an Oxide of Tin. Purpose: Within completing this lab, it was intended for the experimenter (student) to determine the empirical formula of an oxide of Tin by means of experimenting. This goal would be accomplished by finding the masses of the various substances experimented with, which 30 mesh tin, Tin Oxide, and Oxygen.
In Trial 1, the empirical formula of magnesium oxide = Mg2O3. In Trial 2, the empirical formula of magnesium oxide = MgO. A strip of magnesium metal reacts with oxygen in the air to produce magnesium oxide. In order to experimentally determine the percentage composition and empirical formula of magnesium oxide, a piece of magnesium is heated strongly to react with the oxygen in the air.
