Question

EXAMPLE 5. In a compound, atoms of element Y
form ccp lattice and those of element X occupy 2/3rd of
tetrahedral voids. Find the formula of the compound.​

Answer 1

Answer:

No. of atoms of Y=4 ( for c.c.p)

No. of atoms of X=2/3×8=16/3 ( for f.c.c.)

∴ Formula of compound will be X4Y3.

Explanation:

hope this helos u :-)

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 ${A4B3}$.
