A gaseous fuel composed purely of a saturated hydrocarbon (CnH2n+2) is burned with excess air. Orsat analysis of the stack gas shows that it is composed of 9.24% CO2, 0.97% CO, 0.20% H2, 5.13% O2, and 84.46% N2. Air is supplied at 32°C, 745 torr and 83% relative humidity and the stack gas leaves at 750 torr. Calculate the following:% excess air, AFR by mass, Molecular Formula of Hydrocarbon, dew point of stack gas
