Chapter 13.12, Problem 3E

Interpretation Introduction

Interpretation:

Find out the stable phase of the system and mass fraction of the co-existing phases.

Concept introduction:

Mass to mole conversion is given as follows:

$n_i=\frac{m_i}{\text{M}{\text{.W}}_i}$

Here, mass of the component is $m_i$ and molecular weight of the component is $M{W}_i$.

Molecular weight of ethylene glycol n-butyl ether is $118.17\text{g}/\text{mol}$.

Molecular weight of water is $18.01\text{g}/\text{mol}$.

The composition of this mixture in terms of percentage is given as follows:

$x_i=\frac{n_i}{n_i+n_w}\times 100\%$

Here, mole of the component is $n_i$ and mole of the water is $n_w$.
