Chapter 11, Problem 11.6P

Interpretation Introduction

Interpretation:

The radius of chromium atom is given to be $125\text{pm}$ . The density of solid crystalline chromium 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 body centered cubic structure consists of two atoms per unit cell. The edge length in BCC unit cell is calculated by the formula,

$\text{length},l=\frac{4r}{\sqrt{3}}$

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