Combustion analysis
5.50g of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of 128. g/mol, is burned
completely in excess oxygen, and the mass of the products carefully measured:
carbon dioxide
18.91 g
water
3.10 g
Use this information to find the molecular formula of X.
