Problem- Assume that the molal freezing point depression constant of water is 1.86 degrees celsius kg/mol and that the freezing point of water is 0.00 degrees celsius. A. Complete the following reaction showing what ions calcium chloride will produce upon dissolving in water: CaCL2(aq) --> b. Calculate the molarity (in m) of all solutes (that is, all ions in this problem) of .015 m calcium chloride aqueous solution. C. Calculate both the freezing point depression ( ? T ) and the freezing point of 0.15m calcium chloride aqueous solution.
