- A 0509-g sample of an unknown organic compound containing C, H, and O was burned in air to give 1.316 g of CO2 and 0.269 g of H2O. What is the empirical formula for this compound? (a) CHO (b) C2H2O (c) C4H4O (d) CHO4arrow_forwardA compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157 g of the compound produced 0.213 g CO2 and 0.0310 g H2O. In another experiment, it is found that 0.103 g of the compound produces 0.0230 g NH3. What is the empirical formula of the compound? Hint: Combustion involves reacting with excess O2. Assume that all the carbon ends up in CO2 and all the hydrogen ends up in H2O. Also assume that all the nitrogen ends up in the NH3 in the second experiment.arrow_forwardThe combustion of 5.9 g of CXHYNZ yields 13.2 g CO2 and 8.1 g H2O. What is the empirical formula?
