A solid has a structure in which `W` atoms are located at the corners

1.	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 isA. `NaWO_(2)`B. `NaWO_(3)`C. `Na_(2)WO_(3)`D. `NaWO_(4)`
Answer» Correct Answer - B In a unit cell, W atoms at the corner `=(1)/(8)xx8=1` O atoms at the centre of edges `=(1)/(4)xx12=3` Na otoms at the centre of the cube = 1 `W:O:Na=1:3:1` . Hence formula is `NaWO_(3)` .
