Consider an aqueous 4.00m solution of Na3PO4, a compound with useful detergent properties (kb=0.51Cm1). (a) Calculate the boiling point of the soiution on the assumption that it does not ionize at all in solution. (b) Do the same calculation, assuming that the van't Hoff factor for Naa PO, reflectes 100% dissociation into lons. (c) The 4.00m solution boils at 100.115 "C at 1atm. Calculate the van't Hoff factor for the solute in this solution
