There are 4 atoms to the unit cell.
mass unit cell is
4*atomic mass Sr/6.022E23
volume = 2.25E-25L = 2.25E-22 cc.
density = mass/v = ?
The element strontium has ccp packing with a face-centered cubic unit cell. The volume of the unit cell is 2.25 x 10-25 L. Calculate the density (g/mL) of the element.
