Question
Chapter 11.6, Problem 1RCF
Interpretation Introduction
Interpretation:
The density of Lithium fluoride in FCC unit cell has to be calculated.
Concept Introduction:
FCC: In the face-centered cubic (FCC) cell, there will be six faces in a cube and the center of each face has a lattice point. Apart from the six faces, there will be eight corners. One corner atom will be shared by 8 unit cells and a face-centered atom is shared by 2 unit cells.
Density of Lithium fluoride:
Relation between a (edge length) and V (volume) in FCC:
The relation between volume-V and edge length-a, enables to find the volume. Then mass has to be found out which can be divided by the calculated volume to determine the density.
