B C6H12O6 Only

C All three

D NaCl Only

Part #2:

Determine the ideal van’t Hoff Factor for the following: Al(NO3)3

Part #3:

Determine the molality of total solute particles for the following: 0.227 m Al(NO3)3

Part #4:

What is the freezing point of the solution in part 3 in oC? Note: kf of water is 1.86oC/m and pure water freezes at 0.000 oC (note: as this is freezing point DEPRESSION, what will the final sign of the freezing point be?).
