Help! I have to get this done tonight and I cannot get this answer right. A solution of water (Kf=1.86 ∘C/m) and glucose freezes at − 3.55 ∘C. What is the molal concentration of glucose in this solution? Assume that the freezing point of pure water is 0.00 ∘C.

Answer 1

So delta T = 0-(-3.55) = ?
delta T = Kf*m
You know delta T and Kf, solve for m = molality
