For this question imagine that sea water is a 3.5 mass % solution of NaCl with a density of 1.00g/mL. Assume full dissociation of the NaCl.

a) Calculate the freezing point of sea water. Briefly explain why it is not 0 (degrees Celsius).

b) Calculate the osmotic pressure of sea water at 298K. Briefly explain how this relates to the desalination of sea water via reverse osmosis.
