Chapter 11, Problem 11.65QE

Interpretation Introduction

Interpretation:

The number of ${\text{NH}}_{\text{4}}{}^{\text{+}}$ ions and ${\text{Cl}}^{\text{-}}$ ions has to be calculated.

Concept Introduction:

Simple cubic structure (Sc):

In the simple cubic structure there is only one lattice point each corner of cube shaped unit cell.

  The number of atoms present=$\text{Number}\text{of}\text{corners×}\left(\frac{\text{Number}\text{of}\text{atoms}}{\text{Number}\text{of}\text{corners}}\right)$

Body centered cubic structure (Bcc):

The body centred cubic structure is based on the scc but has an additional lattice point at the very centre of the cube.

  The number of atoms present $\text{=}\frac{\text{Number}\text{of}\text{atoms}}{\text{1}}$
