Chapter 17, Problem 69E

Interpretation Introduction

Interpretation : The molar mass of the hydrocarbon should be calculated.

Concept Introduction :

The equation for boiling point elevation;

  $\Delta T=K_b.m_{solute}$

Here,

  $\begin{array}{l}\Delta T\text{ - Freezing point depression}\\ {\text{K}}_{\text{b }}\text{- molal freezing point depression constant}\\ {\text{m}}_{solute}\text{ - molality of the solute in the solution}\end{array}$

  $\text{Molality = }\frac{\text{Moles of solute}}{\text{Kilograms of solvent}}$
