Chapter 14, Problem 111IAE

Interpretation Introduction

Interpretation:

Volume of ethylene glycol should be calculated.

Concept introduction:

For freezing point depression;

$\begin{array}{l}\Delta {\text{T = K}}_f\text{m}\\ \Delta \text{T}=\text{ Temperature difference }\\ {\text{K}}_f=\text{ Frezing point depression constant}\\ \text{m = Molality }\end{array}$

$\begin{array}{l}\text{Molality of the solution = }\frac{\text{Amount of solute (moles)}}{\text{Mass of solvent (kilograms)}}\\ \end{array}$
