Question

Atoms of element x from hcp lattice and those element from occupy 2/3 of the tetrahedral voids. Determine the formula of the compound

Answer 1

Answer:

X3Y4

Explanation:

X=6

y=2/3×12=8

X3Y4

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

• ❤.. The number of tetralhedral voids formed is equal to twice the number of atoms of element B and only 2/3rd of these are occupied by the atoms of element A.
• ❤..Hence the ratio of the number of atoms of A and B is ${2×(2/3):1 or 4:3}$ and the formula of the compound is ${A4B3}$.
