Finding The Empirical Formula of Magnesium Oxide Aim: The aim of this experiment is to burn a known mass of magnesium in air and find the mass of the magnesium oxide produced. Using my results I can then calculate the empirical formula of magnesium oxide. Results: Observations Before starting I notice that the magnesium is very shiny and flexible. After one minute of heating the Magnesium appears to be going white. The Magnesium has caught …

…moles in each element Mg         :         O 0.01         :         0.01 1         :         1 Therefore the empirical formula for Magnesium Oxide is MgO Conclusion: I thought my experiment went very well. I made no errors and I worked quickly enough to finish on time even though I had a bad start. If I were to do this experiment again I will try and work a bit faster and get all my things more organised before the practical. But overall things went very well.
