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

Text Solution

Verified by Experts

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`
