1.	A compound is formed by two elements M and N. The element N forms cep and atoms of M occupy 1/3rd of tetrahedral voids. What is the formula of the compound ?
Answer» SOLUTION :SUPPOSE the atoms N in the ccp= n `therefore`No. of TETRAHEDRAL voids = 2n As `1/3`rd of the tetrahedral voids are occupied by atoms M, therefore, no. of atoms `M="2n"/3` `therefore `RATIO of `M:N="2n"/3:n=2:3` . Hence, the formula is `M_2N_3`
