You find out this chemical splits apart into five ions when dissolved. You then buy a small amount of the mystery chemical, and start conducting freeze point depression experiments (in H₂O), to try and find the Molar Mass of the compound.

Question
You find out this chemical splits apart into five ions when dissolved. You then buy a small amount
of the mystery chemical, and start conducting freeze point depression experiments (in H₂O), to try
and find the Molar Mass of the compound. You use 20.0g of the deicing agent and it depresses the
freezing point of 35.0g of water by 15.4 °C.
What is the molar mass of the deicing agent? (you did this in lab) kf = 1.86 °C*kg/mol
425 g/mol
69.0 g/mol
344 g/mol
88.0 g/mol
