You are given grams of solute and grams of solvent. You must first calculate the molality of CuSO4 solution. Next you use the molality to find the fp and bp changes. fp goes down and bp goes up by specific amounts based on the molality of the solution. This is the most difficult type of Fp Bp based on molality problem type you will ever have. For the 2nd half of this video see Part 2 of the same title.
