What is the formula of a compound in which the element Y forms hcp lattice
and atoms of X occupy 2/3rd of tetrahedral voids
Asked by upasana.sobti | 16 Jan, 2019, 13:59: PM
The no. of atoms in hcp lattice, Y = 6
Tetrahedral void = 2× 6
= 12
2/3 of these voids are occupied by X,
Therefore,
![12 cross times 2 over 3 space equals space 8
therefore space straight X space equals space 8 space space space straight Y space equals space 6](https://images.topperlearning.com/topper/tinymce/cache/8f4042a1d8a8064eb0c1c8269f89fb38.png)
So the formula of a compound formed is X4Y3.
