Question 30

Chromium is industrially extracted from chromium(III) oxide, $Cr2O3\text{Cr}_2\text{O}_3$ , via a high-temperature reduction reaction.

Calculate the maximum mass of pure chromium, in $kg\text{kg}$ , that can be theoretically obtained from 456 kg of chromium(III) oxide, $Cr2O3\text{Cr}_2\text{O}_3$ .

(Relative atomic masses: $O=16\text{O} = 16$ , $Cr=52\text{Cr} = 52$ )
