Think about what you are asking. Can't anything freeze if the temperature is lowered enough?
moles = grams benzoic acid/molar mass
solve for moles benzoic acid.
molality = moles/kg solvent\
m = moles/0.01 kg
delta T = Kf*m
solve for delta T and convert to freezing point.
Can 10.ml of glacial acetic acid mixed with 0.50 g of benzoic acid crystals (dissolved) freeze? And if so, what is the freezing point?
