Unformatted text preview: MgO Conclusion The purpose of this lab was to have the student determine the empirical formula of magnesium oxide and to demonstrate the law of constant composition. The student also practiced finding a constant weight. The results of the experiments were finding that Magnesium Oxide is 63.3% and 37.7% Oxygen. Also we found the mole ratio to be 1:1, therefore making the empirical formula of Magnesium Oxide, MgO. Possible sources of error could be touching the outside of the crucible, therefore getting your oils on it and affecting the final results. Also, not waiting for everything to cool completely could affect the masses. No data was discarded....
