A solution is made by dissolving 0.526 mol of nonelectrolyte solute in 831 g of benzene. Calculate the freezing point and boiling point of the solution. Constants may be found here.

Answer 1

m = 0.526 mol/kg solvent (0.831 kg benzene)
delta T = Kf*m and subtract from zero to find new f.p.
delta T = Kb*m and add to 100 to find new boiling point.
