Question

The combustion of an unknown amount of benzene (x moles of C₆H₆) in pure oxygen in a chemical reactor produces the following dry exhaust gas analysis: 44.71% CO₂ and 55.29% O₂. Determine

a. The actual molar and mass fuel/oxygen ratios.

b. The percent of theoretical oxygen used.

c. The molar percentage of water vapor in the exhaust gas before it was dried for this analysis.
