In a reaction, 37.5 g of chromium(III) oxide reacts with 13.3 g of aluminum to produce chromium and aluminum oxide. If 25.7 g of chromium is produced, what mass of aluminum oxide is produced?
This is a regular stoichiometry problem disguised to appear as a limiting reagent problem. Here is a worked example of a stoichiometry problem. Just follow the steps. http://www.jiskha.com/science/chemistry/stoichiometry.html
