A mixture of butane and propane was used as fuel and it produced 9.2 percent CO2, 1.2 percent CO, 7.5 percent O2 and 82.1 percent N2.

What is the percent x's air; percent analysis of fuel; V (in cubic meter) of air (with 80 percent relative humidity, T=25C, P=760 mmHg); and V (in cubic meter) of the stack (T=400C, P=740mmHg).
