Vapor in a tank

  1. Sep 7, 2007 #1
    Guys..I once again turn to your help.

    There is a certain amount of styrene in a tank at a certain temperature and pressure. i have vapor pressure for styrene at that temp. Can I calculate the amount of styrene in vapor phase and the amount in liquid phase? If so, how?

    One would need the mass of styrene, the specific volumes of liquid and vapor at the given temperature and pressure, and the volume of the tank.

    I can calculate the mass of liquid styrene. The tank is 50,000 gallons with about 65% full with liquid styrene. Do we need the volume of vapor styrene? or just the empty volume above the styrene. I want to calculate the volume of vapor styrene..so I obviously don't have that.
