Carbon hydrogen and oxygen are not the only elements that can be characterized by combustion analysis. If a compound also contains sulfur or nitrogen, then it will form CO2, H2O, N2 and SO2. The amount of oxygen in the original sample is determined from subtracting the masses of the other elements from the total, as in the combustion analysis described. If a 0.500 g sample of a compound yields 0.814 g CO2, 0.204 g H2O, 0.0288g N2, and 0.132g SO2 when burned, then what is its empirical formula?
