I assume this is a non-ionic solution. See my response to your question above or
dT = Kf*m
You know dT and If, solve for m
m = mols/kg solvent. You know m and kg solvent, solve for mols.
Post your work if you get stuck.
The freezing-point depression for a given aqueous solution is 0.32 K. The freezing-point depression constant for water is 1.86 K/m. Calculate the molality of solutes in the solution.
The equation for freezing point depression is ΔTf = Kf · m, where ΔTf is the freezing point depression, Kf is the freezing-point depression constant, and m is the total molality of all solutes in solution.
