High Octane Gasoline Gasoline is a complex mixture of hydrocarbons, including different isomers of octane. Gasoline is sold with a variety of octane ratings that are based on the comparison of the gasoline with the combustion properties of isooctane, a structural isomer of $${\mathrm{C}}_8{\mathrm{H}}_{18}$$. The structure of isooctane and another isomer of $${\mathrm{C}}_8{\mathrm{H}}_{18}$$ are shown in the figure below, along with their normal boiling points and heats of vaporization. Determine the vapor pressure of each isomer on a very hot summer day, $$38.0^{?}\mathrm{C}$$.
