Problem 4. ( 20 points) The following figure shows that n-octane (a pure component) at 187C and 4.25 bar exhibits two phases (gas and liquid). Using only the data from this figure provide: a) Number of millimoles in the gas phase (ne) b) Volume occupied by the gas phase in the cell in cm3(Vg) c) Number of millimoles of n-octane to be added to have a single liquid phase at the same temperature and pressure (n) d) z factor of the gas phase R=83.145cm3barK1mmol1T(K)=T(C)+273.15 Write your answers in the table provided below. Note: 1 millimol =103 moles, this is a mass balance, pay attention to units, intensive, and extensive properties. Problem 4.
