An element with a density of 2.7 × 103 kg m-3 has a molar mass of 2.7 × 10-2 kg / mol and it makes a cubic unit cell with an edge length of 405 pm. What kind of cubic unit cell does it have?
If its density is 2.7 x 103 kg m-3, what is the nature of the cubic unit cell? Applying the relation, This implies that four atoms of the element are present per unit cell. Hence, the unit cell is face-centred cubic (fcc) or cubic close-packed (ccp).
