Chapter 22, Problem 92IAE

Interpretation Introduction

Interpretation:

The density of polonium from the given data should be determined.

Concept introduction:

Density of solid crystal structure can be calculated with the help of:

$\text{d = }\frac{\text{Z }\times \text{ M}}{{\text{a}}^{\text{3}}\times \text{ Na}}$

Here:

d= density (g/cm³)

a= Edge length (cm)

N_A = Avogadro number = $\text{6}\text{.022 }\times {\text{ 10}}^{\text{23}}$

M = Molar mass (g/mol)

Z = Coordination number

For simple cubic structure; Z = 1
