Q. The average gasoline tank in an automobile has a 50 L capacity. Every time the gas tank is filled, the vapor space in the tank is displaced to the environment. Since all forms of hydrocarbons in the atmosphere contribute to the formation of ozone and need to be controlled, this problem attempts to quantify some of these emissions. Assume the automobile tank vapor space, the air, and the gasoline supply is all at 20 degrees C. The vapor space is saturated with gasoline. The vapor-phase mole fraction of gasoline under these conditions is approximately 0.4. The lost vapor has a molecular weight of about 70 g/gmol and a liquid specific gravity of 0.62.
a) Calculate the amount of gasoline (in gallons of liquid) that is lost to the air during a 35 L fill.
b) How much is lost annually from 50 million cars filled once each week with 35 L of gasoline.
Please help with this problem. I'm really stuck.
I would really appreciate it if you could provide the solution to this.
