Chapter 5, Problem 5B.8BE

Interpretation Introduction

Interpretation: The ideal solubility of lead in bismuth at a given temperature has to be calculated.

Concept introduction: Mole fraction is the ratio of the number of moles of a component and the total moles of the solution.  It has no units.  The formula to calculate the mole fraction is,

    $x_{\text{A}}=\frac{n_{\text{A}}}{n_{\text{A}}+n_{\text{B}}}$

Where,

• $n_{\text{A}}$ is the number of moles of A.
• $n_{\text{B}}$ is the number of moles of B.
