Can someone tell me what I need to do to solve a combustion analysis problem? I was assigned homework with the question "A combustion analysis of a 0.503 g sample of an unknown hydrocarbon yields 1.53 g CO2 and 0.756 g H2O. What is the empirical formula of the sample?" I got CH5 when I tried to solve it, but the website we submit our homework through is telling me that's wrong.

Show your calculations. Otherwise we cannot find your error.
