A) \[NaW{{O}_{2}}\]
B) \[NaW{{O}_{3}}\]
C) \[N{{a}_{2}}W{{O}_{3}}\]
D) \[NaW{{O}_{4}}\]
Correct Answer: B
Solution :
In a unit cell, W atoms at the corner \[=\frac{1}{8}\times 8=1\] O atoms at the centre of edges \[=\frac{1}{4}\times 12=3\] Na atoms at the centre of the cube = 1 \[W:O:Na=1:3:1,\] hence formula \[=NaW{{O}_{3}}\]You need to login to perform this action.
