Density of a unit cell is represented as...

Density of a unit cell is represented as
`rho=("Effectiveno.ofatom(s)x Mass of a unit cell")/("Volume of a unit cell")=(Z.M.)/(N_(A).a^(3))`
Where, mass of unit cell = mass of effective no. of atom(s) or ion(s).
M = At. wt./formula wt.
`N_(A)="Avogadro’s no. "rArr 6.023xx10^(23)`
a = edge length of unit cell
