Density Formula
Density is defined as the mass per unit volume.
Contents
It is denoted (rho) ρ.
General formula:
Density of unit cell :
Density of unit cell is mass of unit cell to volume of unit cell.
Mass of unit cell = M× Z
Volume of the cubic unit cell = a×a×a = a3
a is expressed in cm
M mass = g/mol
Density unit = g/ cm3
Avogadro’s number = 6.022 × 1023
Density of mass unit cell:
M = Mass
Z = Atomic number
Na = Avogadro’s number 6.022×1023
a3 = edge length of unit cell
