    Consider a 5.430-g mixture of FeO and Fe3O4. You react this mixture with excess of oxygen to form 5.779g Fe2O3. Calculate the percent by mass of FeO in the original mixture.

    You can start by writing a balanced chemical equation for the reaction.

    Writing one for the reactions, might be better :)

    Writing TWO for reactions will be even better.
