Question

Determine the mass of a nonvolatile, nonionizing compound that must be added to 4.68 kg of water to lower the freezing point to 98.70oC. The molar mass of the compound is 50.0 g/mol and the Kf for water is 1.86oC kg/mol. Ignore significant figures for this problem.
Answer

Answer 1

You need to proof this problem. I don't think the numbers are right. Freezing point of water is -1.86; I don't know how you can add a solvent to it to RAISE the freezing point.
