Chapter 16, Problem 16.6P

Interpretation Introduction

Interpretation:

The mole fraction of calcium in an alloy that is $95.0\%$ lead and $5.0\%$ calcium by mass has to be calculated.

Concept Introduction:

Mole fraction:

Mole fraction of a solute in a solution can be calculated as given below.

  ${\chi }_1=\frac{n_1}{n_{tot}}$

Where, $n_1$ is the number of moles of solute and $n_{tot}$ is the sum of moles of solute and solvent.
