cation A occupies 2/3rd of all the octahedral voids while the anion B is found in all lattice points predict the formula of the ionic compound formed by them

Expert Answer:

Type of crystal lattice is not given.
Let's  assume it is hcp.
Coordination number in hcp=12
 
Cation A is arranged in octahedral voids=12 cross times 2 over 3 equals 8
Number of latttice points in hcp=2
 
Anion B is arranged on lattice points, number of anion B=2
 
A  :   B
8  :   2
4  :   1
 
 
Formula of compound is A4 B1
