 · Solution: Suppose the number of oxide ions (O 2-) in the packing = 90. ∴ Number of octahedral voids = 90. As 2/3 rd of the octahedral voids are occupied by ferric ions, therefore, number of ferric ions 2 present = × 90 = 60. ∴ Ratio of Fe 3+ : O 2- = 60 : 90 = 2 : 3. Hence, the formula of ferric oxide is Fe 2 O 3.
