As a car's gas tank is filled, gasoline vapors in the tank are displaced and may be emitted into the atmosphere. For this problem, assume that the fuel pump is NOT equipped with a vapor recovery nozzle (as are pumps in many areas with poor air quality). Gasoline is a complex mixture of hydrocarbons. Assume that the effective vapor pressure for gasoline at 80F is 0.51 atm and that gasoline vapors are well represented as pentane (C5H12). Also, assume that the gasoline vapors are in equilibrium with liquid gasoline in the fuel tank. Consider a day that is warm and sunny (ambient temperature of 80 F or 27C). Determine the emission rate of gasoline vapors associated with refueling, in units of grams emitted per gallon of gasoline compound.
