Answer:
The theoretical density for Niobium is .
Explanation:
Formula used :
where,
= density of the unit cell
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
We have :
Z = 2 (BCC)
M = 92.91 g/mol ( Niobium)
Atomic radius for niobium = r = 0.143 nm
Edge length of the unit cell = a
r = 0.866 a (BCC unit cell)
On substituting all the given values , we will get the value of 'a'.
The theoretical density for Niobium is .
