Hematite reaction with carbon monoxide

Iron is obtained commercially by the reaction of hematite (Fe203) with carbon monoxide. How many grams of iron are produced if 25.0 moles of hematite react with 30.0 moles of carbon monoxide ... 

In the blast furnaces that produce iron from iron ore, one of the important chemical changes is the reaction of the iron oxide in hematite with carbon monoxide. 

Hematite, Fe203, is an important ore of iron see Figure 3.12. (An ore is a natural substance from which the metal can be profitably obtained.) The free metal is obtained by reacting hematite with carbon monoxide, CO, in a blast furnace. Carbon monoxide is formed in the furnace by partial combustion of carbon. The reaction is... 

In reduction by carbon monoxide the reactions listed above are nearly isoenthalpic (having heats of reaction less than 5 kcal/g-atom oxygen) except for the reduction of hematite to magnetite, which is exothermic with a heat of reaction of approximately 12 kcal/g-atom oxygen at 1000°C.
