A mixture of propane and butane is burned with air. Partial analysis of the stack gas produces the following dry-basis volume percentages: 0.0527% C3H8, 0.0527% C4H10, 1.48% CO. and 7.12% CO2. The...

A mixture of propane and butane is burned with air. Partial analysis of the stack gas produces the following dry-basis volume percentages: 0.0527% C3H8, 0.0527% C4H10, 1.48% CO. and 7.12% CO2. The stack gas is at an absolute pressure of 780 mm Hg and the dew point of the gas is 46.5°C. Calculate the molar composition of the fuel.
