An unknown metal M reacts with Oxygen to give the metal oxide MO2. Identify the metal based on the following information.
Mass of metal : - 0.356 g
Mass of metal oxide: - 0.452 g
A compound containing only C, H, and O, was extracted from the bark of a sassafras tree. The combustion of 91.3 mg produced 248 mg of CO2 and 50.8 mg of H20. The molar mass of the compound was 162 g/mol. Determine its empirical and molecular formu..
