The crystal structure of MgAl2O4 can be described as a face-centered arrangement of anions (O2-) with Al3+ cations in some of the octahedral holes, and Mg2+ cations in some of the tetrahedral holes.
What fraction of the octahedral holes are occupied by Al3+?
What fraction of the tetrahedral holes are occupied by Mg2+?
Can someone please explain how to determine this? I am very lost
