Chapter 14, Problem 32E

Interpretation Introduction

(a)

Interpretation:

The mole faction of ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$ in the aqueous solution needs to be calculated.

Concept introduction:

The mole fraction of any species is calculated as number of moles of that species in total number of moles of solution. For example, for a component A in a solution, the mole fraction can be calculated as follows:

${\chi }_{\text{A}}=\frac{n_{\text{A}}}{n_{\text{total}}}$

Here, $n_{\text{A}}$ is number of moles of component A.

Interpretation Introduction

(b)

Interpretation:

The mole fraction of $\text{CO}{\left({\text{NH}}_{\text{2}}\right)}_{\text{2}}$ needs to be calculated.

Concept introduction:

The mole fraction of any species is calculated as number of moles of that species in total number of moles of solution. For example, for a component A in a solution, the mole fraction can be calculated as follows:

${\chi }_{\text{A}}=\frac{n_{\text{A}}}{n_{\text{total}}}$

Here, $n_{\text{A}}$ is number of moles of component A.

The mole percent of any component in the solution can be calculated as follows:

$\%n=\frac{n_{\text{Component}}}{n_{\text{Solution}}}\times 100\%$
