Relation between Lattice Constant (a) and Density (ρ)
Crystal Physics
In M gram of material, there are N molecules i.e., mass of N molecules is M gram.
Relation between Lattice Constant (a) and Density (ρ) Let a = Lattice constant of a crystal material, ρ = Density of the crystal, n = Number of atoms per unit cell, M = Molecular weight of the crystal material, and N = Avagadro number = 6.023 × 1023 mole-1 In M gram of material, there are N molecules i.e., mass of N molecules is M gram. ⸫ Mass of n molecules (i.e., mass of unit cell) = n × M / N ... (i) But we know that, Mass density = Mass/Volume
