A cube solid is m

Answer :

CCP crystal structure means Cubic Close Packing.

Given that,the ccplattice is formed by the atoms of the element A. As the number of tetrahedral voids generated is equal to twice the number of atoms of the element (A), and, according to the , the atoms of element B occupy 1/3rd of the tetrahedral voids, so:

Number of atoms of B is equal to 2 × ()=rd of the number of atoms of A.

The ratio of the number of atoms of B to that of A is B:A =2:3. Thus, the formula of the compound is B2A3.
