a) The methane (CH4) gas in a 10.00L container at 305oC and 101 kPa pressure was burned in excess oxygen. What is the mass of carbon dioxide added to the atmosphere from this combustion?
b) A gaseous hydrocarbon with the empirical formula CH2 was placed in a 2.00L container. At a temperature of 101oC the pressure was 755 Torr and the mass of the hydrocarbon was 1.812g. What are the values of the integer a and b for this molecular formula (CaHb)?
