When a 5.712 g sample of an organic compound containing C, H, and O is burned completely in oxygen, 8.1 g of CO2 and 4.956 g of H2O are produced. What is the empirical formula of the compound?

While working in the lab, you find a bottle of white powder labeled "astringent". Since the original investigator neglected to record the identity of the substance, you decide to perform a combustion analysis to identify the compound. You have a 76.8 g sample that when burned produces 139 g CO2 and 24.4 g H2O. What is the empirical formula of this compound? (The compound consists of only C, H, and O.)
