Question

In a ccp lattice made up of Y anions, all the tetrahedral voids are occupied by X cations. Predict the formula of the solid.

Please give answer with complete step by step explanation as soon as possible .​

Answer 1

Explanation:

ccp atoms/cell = 4

X = 4

Y = Tetrahedral void ; so it will have double no. of atoms

Therefore, Y = 8

• Hence, req. formula = X4Y8 = XY2
