In a crystal AB having NaCl structure. A atoms occupy the coiners of the cubic unit cel. If all the face centre atoms along one of the axes are removed, what will be the resultant stoichiometric formula of the solid.

In a face centred cubic arrangement of A and B atoms whose A atoms are at the corner of the unit cell and B atoms are at the face centres. One of the A atom is missing from one corner in the unit cell. What will be the result our formula of the compound formed?

A compound formed by elements A and B crystallises in the cubic structure where A atoms are at the corners of the cube and B atoms at the centre of the cube. What is the formula of the compound?
