Expert Answer:
It is given that the atoms of Q are present at the corners of the cube.
Therefore, number of atoms of Q in one unit cell
It is also given that the atoms of P are present at the body-centre.
Therefore, number of atoms of P in one unit cell = 1
This means that the ratio of the number of P atoms to the number of Q atoms, P:Q = 1:1
Hence, the formula of the compound is PQ.
The coordination number of both P and Q is 8.
