In a solid ,oxide `(O^(2-))` ions are arranged in ccp, cations `(A^(3+))` occupy one -sixth of tetrahedral void and cations `(B^(3+))` occupy one -third of the octahedral voids . What is the formula of the compound?

Text Solution

Verified by Experts

The correct Answer is:
2
Void volume=0.22/unit volume of unit cell 0.11A =0.22 `rArrA=2`
