A compound is formed by two element M and N . The element N forms ccp and atoms M occupy `frac{1}{3}` of the tetral voids. What is the formula of the compound?

Explanation

Let the number of atoms of N be .n.
`therefore` number of tetrahedral voids = 2n
Number of atoms M = `frac{1}{3}xx2n=frac{2n}{3}`
`therefore` Ratio of atoms M and N = frac{2}{3}n:n=frac{2}{3}:1=2:3` Formula is `M_2N_3`
