The SI base unit for amount of substance is the mole. 1 grams Cr2O3 is equal to 0.006579362907131 mole.

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.
