A. If an aqueous solution is prepared with molality= 4.58 moles of glycerine/100 kg water, calculate the freezing point of the solution. Kf for water = 1.86C/m. (Glycerine is a molecular solute)
b. if an aqueous solution is prepared with molality = 8.21 moles of magnesium chloride/100kg water, calculate the freezing point of the solution. Note : the ionic formula of this salt is MgCl2.
C. Calculate the boiling pointof the solution described in question 2b. Given Kb for water=0.520C/m.
