A compound is formed by two elements M and N . The element N forms ccp and atoms of M occupy `(1)/(3)` rd of tetrahedral voids . What is the formula of the compound ?
i) Find the number of tetrahedral voids as number of tetrahedral voids = `2 xx ` number of atoms present in the lattice .
ii) Calculate the number of atoms (or ratio) of elements M and N as a chemical formula represents the number of atoms of different elements presents in a compound .
iii) Derive the formula .
