Answer:
25.41 g/mol is molar mass of metal.
Explanation:
Number of atom in BCC unit cell = Z = 2
Density of metal =
Edge length of cubic unit cell= a = ?
Radius of the atom of metal = r =
Atomic mass of metal =M
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'.
25.41 g/mol is molar mass of metal.
