Crocetin consists of elements carbon, hydrogen and oxygen. Determine the empirical formula of crocetin, if 1.00g of crocetin forms 2.68g of carbon dioxide and 0.657g of water when it undergoes complete combustion. This is what i did: 2.68/44.01=0.0609 mols of carbon dioxide. 0.657/18.02=0.0365 mols of water.
