When a mixture of aluminum powder and iron(III) oxide is ignited, it produces molten iron and aluminum oxide. In an experiment, 5.40 g aluminum was mixed with 18.50 g iron(III) oxide. At the end of the reaction, the mixture contained 11.17 g iron, 10.20 g aluminum oxide, and an undetermined amount of unreacted iron(III) oxide. No aluminum was left. What is the mass of the unreacted iron(III) oxide?
