Chemistry help beware: moles inside!

  1. Oct 5, 2004 #1
    Ok chemistry is my WORST subject... so go ahead and laugh first.

    ahem.

    I have this question that I can't seem to figure out the answer for... or more likely just figure out how to start... here it is:

    A 2.5783 g mixture containing malachite and an inert ingredient lost 0.3121 g of H_2O and CO_2 (... i know i know) when decomposed by heating to constant mass...

    -- How many moles of malachite in the mixture produced this mass of CO_2 and H_2O?


    The thing is I'd think I know how to do it with an equation telling me ratios. With this it's just.. I don't know what to do since I don't know the ratio of malachite moles in that equation to H_2O and CO_2...

    :(
