Explain the density of the compound as a gas was found

Reference no: EM13518073

An organic compound contains C, H, N, and O. Combustion of 0.1023g of the compound in excess oxygen yielded 0.2766g of CO2 and 0.0991g of H2O. A sample of 0.4831g of the compound was analyzed for N by the Dumas method. At STP, 27.6mL of dry N2 was obtained. In a third experiment, the density of the compound as a gas was found to be 4.02g/L at 127 degrees C and 256 torr. What are the empirical and molecular formulas of the compound?
