Chapter 16, Problem 69E

Interpretation Introduction

Interpretation:The edge length and density of KCl needs to be calculated.

Concept Introduction:The mathematical expression for the density of the unit cell is:

  $\text{density = }\frac{\text{zM}}{{\text{a}}^{\text{3}}{\text{N}}_{\text{A}}}$

Where z represents number of atoms/molecules present in the unit cell, M is the molar mass, a is the edge length and ${\text{N}}_{\text{A}}$ is the Avogadro’s number.
