Chapter 12, Problem 102AE

Interpretation Introduction

Interpretation:

The given data is to be used to calculate and compare densities of nickel and ${\text{Ni}}_{\text{3}}\text{Al}$ .

Concept introduction: Density of ${\text{Ni}}_{\text{3}}\text{Al}$ is lower than $\text{Ni}$ , hence it is used in the manufacturing of aircraft engines. Nickel metal has a cubic close packed structure with a face-centered cubic unit cell while ${\text{Ni}}_{\text{3}}\text{Al}$ has the ordered cubic structure.

To determine: The comparison of densities of nickel and ${\text{Ni}}_{\text{3}}\text{Al}$ using the given data.
