A solid has a structure in which `W` atoms are located at the corners of a cubic lattice, `O` atom at the centre of edges, and `Na` atom at the centre of the cube. The formula for the compound is

A

`NaWO_(2)`

B

`NaWO_(3)`

C

`Na_(2)WO_(3)`

D

`NaWO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
Contibution by atoms of W at the corners
`=1//8xx8=1`
Contribution by atom of 'O' at the edges `=12xx1/4=3`
Contribution by Na atoms in the centre of the cubic =1
:. Formula is `NaWO_(3)`
