determine the amount of solute needed to make 100ml aqueous solution of NaCl and MgCl2 that will cause a 10 degree change in freezing point. Determine the amounts of solute needed to make 100ml aqueous of AlCl3 and ethanol that will cause a 10 degree change in boiling point.

Use the same system used for the KBr, Al2(SO4)3. Mg(NO3)2 problem EXCEPT use Kb for the boiling point constant instead of Kf (the freezing point constant).
i = 4 for AlCl3
i = 2 for NaCl
i = 1 for ethanol
i = 3 for MgCl2
