A compound formed by two elements `M` and `N`. Element `N` forms ccp and atoms of `M` occupy `1//3rd` of tetrahedral voids. What is the formula of th compound?

Explanation

To find the formula of the compound formed by elements M and N, we can follow these steps:

### Step 1: Determine the structure of element N
Element N forms a cubic close-packed (CCP) structure. In a CCP structure, there are 4 atoms of the element per unit cell.

### Step 2: Calculate the number of tetrahedral voids
In a CCP structure, the number of tetrahedral voids is given by the formula:
\[ \text{Number of tetrahedral voids} = 2 \times \text{Number of atoms in the unit cell} \]
