Chromium is industrially extracted from chromium(III) oxide, Cr2O3\text{Cr}_2\text{O}_3Cr2O3, via a high-temperature reduction reaction.
Calculate the maximum mass of pure chromium, in kg\text{kg}kg, that can be theoretically obtained from 456 kg of chromium(III) oxide, Cr2O3\text{Cr}_2\text{O}_3Cr2O3.
(Relative atomic masses: O=16\text{O} = 16O=16, Cr=52\text{Cr} = 52Cr=52)
