Now cross multiply again between the numbers above and below the Cr2O3 and the Cr and solve for X grams of Cr2O3. X = 14.61 grams of Cr2O3 Cr2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Cr3+ is bonded to six equivalent O2- atoms to form a mixture of edge, corner, and face-sharing CrO6 octahedra. The different oxidation states of chromium allow its bulk oxide form to be reducible, facilitating the oxygen vacancy formation process, which is a key property in applications such as catalysis.
