A gaseous hydrocarbon fuel is burned in 26.84% excess oxygen and the exhaust gas analyzed. On a dry basis, the ratio of carbon dioxide to carbon monoxide to oxygen in the exhaust gas is 60:6:34 (ratio of CO2:CO:O2). The fuel contains no sulfur or water and 100% of the fuel burns.
a.) How many moles of carbon are in the fuel?
b.) How many moles of water are in the exhaust gas?
c.) What is the ratio of carbon to hydrogen in the fuel?
d.) How many moles of gas are fed?
e.) How many moles of oxygen are fed?
