The first step of the production of metallic iron from iron ore (iron(III) oxide, Fe2O3 ) is reaction of Fe2O3 with carbon monoxide, CO: 3Fe2O3+CO==2Fe3O4+CO2 You invent a clever device that can count individual molecules and use it to measure the number of carbon dioxide molecules that are produced by burning a quantity of Fe2O3. Your device showed that 2.81025 molecules of CO2 were produced. How many molecules of Fe3O4 were produced along with the CO2 ? Cannot be calculated from the information given 2.81025 molecules of Fe3O4 5.61025 molecules of FejjO4 1.41025 molecules of Fe3O4
