Empirical Formula of Magnesium Oxide

It's one of the "classic" experiments in school chemistry, combusting (burning) some magnesium in a crucible to make magnesium oxide.
While the lab questions usually focus on identifying that a chemical change has occurred, and calculating either percentage composition and/or empirical formula of magnesium oxide, I wonder how many students are really thinking about the experiment?
So, AUS-e-TUTE has written a tutorial that (hopefully) will help students think about why certain procedures are followed, and the kinds of errors one can expect.

AUS-e-TUTE members should log-in to use the new tutorial, game and test.

If you are not an AUS-e-TUTE Member, a "free-to-view" tutorial is currently available for evaluation purposes at

Information about AUS-e-TUTE Membership is available at
