Gasoline is a mixture of hydrocarbons, a major component of which is octane, CH3CH2CH2CH2CH2CH2CH2CH3. Octane has a vapor pressure of 13.95 torr at 25?C and a vapor pressure of 144.78 torr at 75?C. Use these data and the equation in part (a) to calculate the heat of vaporization of octane.

Express your answer using two significant figures.
