1) Find out the normal boiling point in Celsius of pure acetic acid giving that the liquid has a vapor pressure of 13.9 torr at 25degree Celsius and its heat of vaporization (Δhvap) is 41.7kj/mol.
2) Explain a mixture of ethanol (C2H5OH; 46.0G/mol p= 108.0 mmhg) and1-propanol (C3h7OH; 60.1 g/mol, P=40.0mmHg) behaves preferably at 36 degrees Celsius. If the concentration of 1-propanol in the liquid solution is 6.00 M and the density of the solution is 0.810 g/mL, find out the total pressure of the vapor over the solution (both are volatile)
