A solid crystal is composed of X, Y and Z atoms. Y atoms are occupying 50% of octahedral voids, where as X atoms are occupying the 100% tetrahedral void with Z atoms in ccp array arrangement, then the rational formula of the compound in the given crystal is (A) X8Y2Z4 (B) X5Y10Z8 (C) X4YZ2 (D) X16Y4Z8

(A) X8Y2Z4 (B) X5Y10Z8
(C) X4YZ2 (D) X16Y4Z8
Z atoms are in ccp array so no of Z atoms=4no of octahedral voids=4no of tetrahedral voids=8so no of Y atoms=2no of X atoms=8so formula X8Y2Z4 that means X4YZ2 correct answer is CSher mohammadFaculty askiitians
