Chapter 9.8, Problem 26P

(A)

Interpretation Introduction

Interpretation:

Does the mixture behave as an ideal solution?

(B)

Interpretation Introduction

Interpretation:

What percentage different from the ideal solution value is the experimental value?

Concept Introduction:

The expression to obtain the mole fraction is,

$x_1=\frac{n_1}{n_1+n_2}$

The expression to obtain the percentage difference is,

$\%\text{Difference}=\frac{V_{\text{New}}-V_{\text{G}}}{V_{\text{G}}}\times 100$

Here, new volume is $V_{\text{New}}$ and given volume is $V_{\text{G}}$.
