Answer:
The unit cell's edge length is
Explanation:
Number of atom in BCC unit cell = Z = 2
Density of barium metal=
Edge length of cubic unit cell= a = ?
Atomic mass of Ba(M) = 137.33 g/mol
Formula used :
where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
On substituting all the given values , we will get the value of 'a'.
The unit cell's edge length is
