A binary liquid mixture of ethanol (A) and acetone (B) follows non-ideal behavior. The mole fractions of A and B are 0.4 and 0.6, respectively. The vapor pressures at 60°C are 100 kPa (A) and 80 kPa (B). Given activity
coefficients of VA = 1.3 and VB = 1.2, what is the total pressure of the system?
