Asked by Jake
What is the freezing point of a solution of 1.17g of 1-naphthol, C10H8O, dissolved in 2.00ml of benzene at 20 degrees C? The density of benzene at 20 degrees C is 876g/ml. Kf for benzene is 5.12 degrees C/m, and benzene's normal freezing point is 5.53 degrees C.

moles = grams/molar mass
Solve for moles.
molality = moles/kg solvent
Solve for molality.
delta T = kf*m
Solve for delta T and convert to freezing point.
You will need to use density to convert from volume to grams or kg.
