Chapter 16, Problem 147CP

Interpretation Introduction

Interpretation: The metal needs to be identified with its density.

Concept Introduction: The density of any substance can be calculated as follows:

  $d=\frac{m}{V}$

Here, m is mass and V is volume.

The closest packing structures are explained as most space-efficient and regularly packed structures. This is usually seen in crystals where lattice gives the closest packed structures. In the cubic closest packing, the layers of the closest packed spheres are arranged in such a way that every third layer is laying over one another. A unit cell is defined as the smallest repeating portion in the crystal lattice.
