The total volume occupied by the particles in a cubic unit cell is `5xx10^(-23)cm^(3)`. The edge length of the unit cell is 0.407 nm. How many particles are present in the unit cell?

Text Solution

Verified by Experts

Packing efficiency = `(5xx10^(-23))/((0.407xx10^(-7))^(3))=0.74`
Therefore, it is face-centred cubic unit cell. The particles present in this type of unit cell = 4
