1.	A compound is forned by two elemets X and Y , Atoms of the element Y (asanions)make ccp and those of the element X (as cations)occupy all the octahbedral voids. What is the formula of the compound ?
Answer» SOLUTION :SUPPOSE number of atoms Y in ccp =n As number of OCTAHEDRAL voids = No. of atoms in ccp : No of cotahedral voids = n As alll the octahedral voids AR occupied by atoms X , therefore, number of atoms X = n . Ratio of X :Y = n: n = 1:1. Hence the formula of the compound is XY.
