Question

A solid has a structure in which 'A' atoms are located at the corners of a cubic lattice 'B' atom at the center of the edge and C atoms at the center of the cube. The formula for the compound is:

​

Answer 1

Answer:

In a unit cell W atoms at the corner =  

8

1 ​  

×8=1

O atoms at the center of edges =  

4

1 ​  

×12=3

Na atoms at the center of the cube =1

So,  W:O:Na=1:3:1

Hence, formula is NaWO
