A mixture with the total composition given below is at equilibrium at 200 Í¦ F and 400 psia.
Calculate the compositions of the gas and liquid. (Hint: Follow the example 12-4)
Component          Composition
                           Mole percent
Propane                      0.65
n-Butane                      0.30
n-Pentane                   0.05
                              Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì…

2.Calculate the bubble-point pressure of the following mixture at 140F. First assume the ideal-solution behavior (example 12-2). Then, find the bubble-point of a real liquid (example 12-6).
Component       Composition
                        Mole percent
Propane                   0.02
n-Butane                0.40
n-Pentane                0.15
n-Hexane                0.30
n-Heptane                0.13
                        Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì… Ì…

3. Calculate the dew-point pressure of the mixture in Problem 2 at 140F. First assume the ideal-solution behavior (example 12-3). Then, find the dew-point of a real liquid (example 12-7).
