1.	What is the formula of a coumound in which the element Y forms ccp lattice and atoms X occupy 1/3rd of tetrahedral voids ?
Answer» Correct Answer - `X_(2)Y_(3)` Let the number of atoms of Y in ccp lattice = n Number of tetrahedral voids = 2n Since only 1/3 of tetrahedral voids are occupied by the atoms of the elements X Number of atoms of X in ccp lattice = `2nxx1//3=2n//3.` Ratio of X:Y is 2n/3 : n = 2 : 3 Formula of the compound = `X_(2)Y_(3)`.
