Purpose : The purpose of this experiment is to perform an experimental technique in order to find the empirical formula for magnesium oxide. Introduction : In order to determine the empirical formula of magnesium oxide, magnesium will be burnt in the air. Doing this will cause a reaction of the magnesium and the oxygen in the air, as shows the following reaction; MgO O Mg 2 2 2 2 2 + - + Before this reaction simply consists of magnesium oxide, magnesium nitride is also formed while the magnesium strip is burning in the air. In order to get simply the oxide, the magnesium nitride must be heated again with water, replacing the nitrogen in the compound with oxygen, and creating ammonia. Through several masses taken several times, the number of moles of each element in the compound can be determined. With this, the empirical formula can be found. Data
