a) What equation describes the relationship between the fugacity of the saturated liquid (fL) and the fugacity of the saturated vapor (fV), at the saturation temperature and pressure?
b) What is the vapor pressure of this fluid at the isotherm temperature?
c) If the molecular weight of this fluid is 77.1 g/mol, what is the mass density of the saturated liquid?
d) What is the compressibility factor (Z) of the fluid at P = 15 atm if the isotherm temperature is T = 250 ưC? R = 0.08206 LĆĀ·atm/molĆĀ·K.
Using the isotherm plotted on the P-V diagram, answer the following questions. The two areas between the solid and dashed line are equal in magnitude.
