Chapter 11, Problem 12SAQ

Interpretation Introduction

Interpretation:

The radius of rhodium atom is given to be $135\text{pm}$ . The density of crystalline rhodium in $\text{g}/{\text{cm}}^3$ is to be calculated.

Concept introduction: Unit cell is the term used to express the sequential unit of atoms in lattice structure. The edge length in a face-centered cubic unit cell is calculated by the formula,

$l=2\sqrt{2}\times r$

To determine: The density of crystalline rhodium in $\text{g}/{\text{cm}}^3$ .

Correct answer: The correct option is (b).
