A metal crystallizes in bcc unit cell. The atomic mass of the metal is 55.8 g/mol^1
, density = 7.9 g/cm^3
. Calculate the edge length of the unit cell?

Dear student,

Given,
For BCC Z=2
density = 7.9 g/cm3
atomic mass = 55.8 g/mol
edge length (a) = ?
Formula used :
a3 = Z ×Md × NAa3 = 2 × 55.87.9 ×6.022 × 1023a3 = 23.4 × 10-24a = (23.4 × 10-24)13a = 2.86 × 10-8 cmThe edge length of metal is 2.86 × 10-8 cm

Regards
