When a 0.6333-g sample of a compound of carbon, hydrogen and sulfur was burned in excess oxygen, 0.9272 g CO2, 0.3795 g H2O and 0.6749 g SO2 were obtained. In a separate experiment, it was found that, for fixed temperature and pressure, a 0.100 L sample of this compound takes 1.73 times longer to effuse than does a 0.100 L sample of Ar(g). What is the molecular formula of the compound? , draw Structures for the molecule (1 bonus mark for every acceptable structure, up to a maximum of 5 bonus marks).
