. A compound is formed by two elements M and N. The element N forms ccp and atoms of M occupy 1/3rd of tetrahedral voids. What is the formula of the com


Best Answer

Ans.The formula can be determined by using the following method Let the number of atoms of the element N = n Number of tetravalent voids = 2n

It is given that the atoms of element M occupy 1/3 of the tetrahedral voids.

So that the number of atoms of M = (1/3) × 2n

Ratio of the number of atoms of M and N 

M:N =2n/3:n

Multiplying the 3 and pide by n we get

M:N = 2:3

Hence, the formula of the compound is M2N3 .
