Chapter 10, Problem 84QAP

Interpretation Introduction

Interpretation:

The mole percent of methyl alcohol is to be determined in the mixture of both alcohols.

Concept introduction:

The formulas to calculate the mole percent of methyl alcohol is given below:

  $\text{Mole percent of methyl alcohol=}\frac{\text{number of moles of methyl alcohol(x)}}{\text{total number of moles of mixture of alcohol(x+y)}}\text{×100\%}$

And

  $\Delta T_f=k_{f}m$

  $\text{Total number of moles=}\frac{\text{mass}}{\text{Molar mass}}$

  $\text{molality=}\frac{\text{Moles of solute }}{\text{mass of solvent}}$
