The combustion of an unknown amount of acetylene (x moles of C2H2) with pure oxygen in an oxyacetylene torch produces the following dry exhaust gas analysis: 39.14% CO2 and 60.86% O2. Determine
a. The actual molar and mass fuel/oxygen ratios.
b. The percent of excess oxygen used.
c. The molar percentage of each combustion product before the exhaust gas was dried for this analysis.
