a 0.562 g sample of an unkown substance was dissolved in 17.4 g benzene. the freezing point of the solution was 4.075 degrees celcius. the freezing point of pure benzene is 5.455 degrees celcius. for benzene, Kf=5.065 degrees celcius/m and Kb=2.61 degrees celcius/m. assume that the solute is a non-electrolyte.

a. what is the molality of the solution?
b. what is the molar mass of the unkown?
c. if the boiling temperature of pure benzene is 80.2 degrees celcius, what is the boiling temperature of the solution?
d. what is the van't Hoff factor? explain whether one was neccessary in these calculations
