##### Reference no: EM13515836

A sample of unknown material containing C,H,& O is analyzed to determine the molecular weight. A 1.25g sample is burnt and produces 1.72g of CO2. A second sample weighing 0.78g is also burnt and 0.878g of water is collected. In addition, the molecular weight is about 120 g/mole. what is the molecular formula
