Chapter 16, Problem 138AE

Interpretation Introduction

Interpretation: The density of given solid aluminium 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.
