Question

A metal has a fcc lattice. The edge length of the unit cell is 404 pm. The density of the metal is 2.72 gm-cm-3. The molar mass of the metal is :-

Options

A.20 gm- mol-1 
B.40 gm- mol-1 
C.30 gm- mol-1 
D.28 gm- mol-1 

Solution

for FCC, Z = 4
a = 404 pm = 404 × 10-10 cm.

M = 27 gmol-1
