Chapter 16, Problem 16.83P
Interpretation Introduction

Interpretation:

The molality of ethylene glycol in water solution that freezes at 40C has to be calculated.

Concept Introduction:

Freezing point depression:

The lowering of the vapor pressure of a solvent by a solute leads to a lowering of the freezing point of the solution relative to that of the pure solvent.  This effect is called as the freezing point depression.  The mathematical relationship is given below.

  ΔTf=TfTf=Kfmc

Where, ΔTf is freezing point depression, Tf is the freezing point of solution, Tf is the freezing point of pure solvent, Kf is the freezing point depression constant and mc is the colligative molality.
