The equation for the complete combustion of propane is
C3H8+5O2→3CO2+4H2O \text{C}_3\text{H}_8 + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O} C3H8+5O2→3CO2+4H2OWhat is the mole fraction of propane in a mixture of propane and oxygen with the minimum amount of oxygen needed for complete combustion?
