Na = cube center = 1 atom
0 = edge center = 3 atoms (12 edges × 1/4 atom)
w = cube corners = 1 atoms (8 corners × 1/8 atom)

N.a.: o : w = 1 : 3 : 1
3Na : 2O : 3W = 6:6:6 ( equal proportions take lcm)

molecular formula Na3 O2 W3

In a unit cell W atoms at the corner

= 1/8 x 8 = 1

0-atoms at the centre of edges = 1/4 x 12 = 3

Na-atoms at the centre of the cube = 1

W: 0: Na = 1:3:1

Hence, formula is NaW03
