Question

Spinel is an important class of oxide having two types of metal ions. A type of spinel has a ccp arrangement of O^2- ions, in which Fe²⁺ cations occupy $1/ 8^{th}$ of the tetrahedral voids and Fe³⁺ cations occupy half of the octahedral voids. If ' $a$ ' is the edge of the unit cell, then the formula of spinel is -
