1. The organic compound triphenylmethane (C19H16) when pure melts at 171.04 degrees c. When 1.92 grams of hexachlorobenzene (C6CL6) is mixed with 3.74 grams of triphenhlmethane, the melting point of the mixture is 163.19 degrees calcius. Calculate the freezing point depression constant of triphenymethane.

mols solute = grams/molar mass
Solve for mols solute.

m = molality = mols solute/kg solvent
Solve for m

delta T = Kf*m
Solve for Kf
