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 ? |
|
Answer» Suppose the atoms N in the ccp = n No. of tetrahedral voids. = 2n . As ` 1/3` rd of the tetrahderal voids are occupied by atom M, therefore, no. of atoms M ` = (2n)/3` Ratio of M : N `= (2n)/3 : n = 2:3` Hence , the formula is ` M_(2)N_(3)` |
