Question

A cubic solid is made up of two elements X and Y. Atoms of X are present on every alternate corner and one at the center of cube. Y is at rd 1 of the total faces. The empirical formula of the compound is

(A) X2Y1.5
(B) X2.5 Y
(C) XY2.5
(D) X1.5 Y2

Prashant Kotian · Accepted Answer

Correct answer: B. X = 4 [corner] 8 1 + 1[Body center] = 2 1 + 1 = 2 Y = 3 1  [Face center] 2 = 1 Formula  X3/2 Y1 = X1.5Y1
