I know the formula for figuring out moles. However, the problem gives an overall amount, 0.4647g, and says that it contains elements C, H, and O. How do you find the number of moles for each element?

You must post your question again. I'm sure that there is a combustion to give a certain amount of CO2 and H2O. Or there is a % given of each element. Finally, you're asked to give the empirical and/or molecular formula for the compound.

Add the grams of all three CHO. then use the 0.4647 divide by the sum of the CHO and you get the number of moles.
