This is from Kaplan's Qbank...
What is the freezing point of a saturated aqueous solution of 0.1 m lithium fluoride (Kf = -1.86 K/m)?
The answer is supposedly -0.186 degrees Celsius because delta T = (-1.86 K/m)*(0.1 molal).
But what about the van't Hoff factor? Shouldn't everything be multiplied by 2 to account for the dissociation of lithium fluoride into two ions?
