Homework Help: Determining the empirical formula of Magnesium Oxide

  1. Nov 3, 2008 #1
    1. The problem statement, all variables and given/known data
    I already did the experiment but I'm trying to answer a question which asks"

    Suppose that you allowed some magnesium oxide smoke to escape during the experiment. How would the Mg:O ratio have been affected? Would the ratio have decreased, increased or stayed the same? Explaine using calculations.

    2. Relevant equations
    I already know the empirical formula is MgO

    3. The attempt at a solution
    I think it will stay the same because you can't really reduce the ratio any furthur but I don't know how to show it using calculations. please help and thanks.

    You are probably right however keep in mind that I do not know the context of the experiment.
