ANNA UNIVERSITY SOLVED PROBLEMS

Problem 1.3

Calculate the lattice constant of Fe.

Given: density of iron 7860 kg/m3, atomic weight 55.85 and Avagadro's number 6.023 × 1026 atoms/mol

Given data

Density of iron ρ = 7860 kg m-3

Atomic weight M = 55.85

Avagadro's number N = 6.023 × 1026 mol-1

Number of atoms per unit cell (BCC) = 2

Solution

We know that

Substituting the given values, we have

Taking cube root on both sides, we have
