To make homemade ice cream. You fill a pot with 1.50kg of water, and dissolve 175g of CaCl2(MW=110.98g/mol) into it.

A. Freezing point depression constant of water is 1.68degC./m. What will be the freezing point of the salt/water mixture be?

B.From the ice cream, you have kidney trouble and decide to use the CaCl2/water mixture from part A in a dialysis machine. If the density of the solution is 1.05g/ml and temp is 25.0degC. What will be the osmotic pressure?

C. Out of CaCl2 to make ice, so you dissolve 75g of the random chemical on a shelf in 850g of water. The resulting mixture freezes at -3.90degC. What is the molecular mass of the mystery chemical? (Assume it doesn't ionize, so i=1)
