Question

A solid is formed by two elements p and q.The element q forms cubic close packing and atoms of p occupy one third of tetrahedral voids.The formula of the compund is

Answer 1

i think it will b p2q3

Answer 2

Answer:

P2Q3

Explanation:

Number of ions in cubic close packing be N

Then, number of tetrahedral voids will be 2N

The number of ions of Q=N and the number of ions of P=2N/3

Ratio of P:Q = 2N/3:N

                    = 2:3

Thus, the formula will be P2Q3
