Question 11
Gasoline is made up of hydrocarbons such as heptane ($\mathrm{C_7H_{18}}$) and hexane ($\mathrm{C_6H_{14}}$). When they burn, they produce water ($\mathrm{H_2O}$) and carbon dioxide ($\mathrm{CO_2}$). If you burn equimolar quantities of heptane and hexane, the former requires more oxygen gas ($\mathrm{O_2}$) than the latter. Calculate by how many % more $\mathrm{O_2}$ gas heptane requires relative to the same molar quantity of hexane.
