Question

The qualitative analysis of an organic compound showed C, H, O in combustion analysis of 0.20 34 g of a compound gave 0.5 911 g of CO2 and 0.10 36 g of H2O. the molecular weight of the compound was determined by the freezing point pressure method and was found in 210 from the above experimental results. determine the molecular formula of the compound

2. A compound is shown by qualitative analysis to contain carbon nitrogen oxygen and hydrogen combustion experiment on 1.577 mg of it give 4.10 mg of CO2 and 1.02 mg of H2O it was also found to contain 4.74% of Nitrogen if the weight determination by mass spectroscopy gave the value of 287 determine its molecular formula

The qualitative analysis of an organic compound showed carbon hydrogen oxygen in combustion analysis of 0.2034 g of a compound gave 0.5911 of CO2 and 0.1036g of H2O. the molecular weight of the compound was determined by the freezing point pressure method and was found in 210 from the above experiment results. determine the molecular formula of the compound.
