Part D. A 28.50 g sample of a compound of carbon, sulfur, hydrogen, and combusted (burned). 35.25 g CO2 and 14.65 g SO2 were produced. The analysis for hydrogen showed that the compound was 8.514% by mass hydrogen. The molar mass of the compound is believed to be 500 ± 5 g/mole. First find the empirical formula then derive the molecular formula of the compound. oxygen was
