A metallic element exists as a cubic lattice. Each edge of the unit cell is 2.88 A°. The density of the metal is 7.20 g cm–3. How many unit cells will be there in 100 g of the metal?
solution:
we have given a= 2.88A0
Density = 7.20g cm-3
mass = 100g
Volume of the unit cell =
Volume of 100g of the metal
No. of unit cell in
