Homework Help: Chemistry

Posted by Student on Thursday, January 27, 2011 at 10:50am.

Complete combustion of 7.70 g of a hydrocarbon produced 23.7 g of CO2 and 10.9 of H2O. What is the empirical formula of the hydrocarbon?

I first calculated the moles of both the carbon dioxide and the water, but I have no idea where to go from there. Any assistance would be greatly appreciated, thanks!
