Question

) in a compound. Atoms of element y form ccp lattice and those of x occupy 2/3rd of tetrahedral voids. The formula of the compound will be :

Answer 1

number of tetrahedral voids is equal to the coordination number
in CCP coordination number is 4=y

x=(2/3)4
simplifying this to get simplest ratio we get
y(3)x(2) which is the formula

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 ${A4B3}$.
