How do you ensure that the starting material was pure magnesium, and that the reaction to form the oxide product had gone to completion?

You cannot be 100% sure, because at any time, there will be some impurities. But you can get a reasonable purity if you clean the magnesium ribbon well.

And I'm not sure what the empirical formula is mentioned...
