Question:

Iron metal can be refined from the mineral hematite (Fe₂O₃). One way of converting the mineral to iron is to react it with carbon monoxide, as shown below:

Because the hematite is obtained from various ores, it is usually not in a pure form. Suppose an iron manufacturer has 2.00 × 10⁵kg of ore available, and the ore is 93% Fe₂O₃ by mass. (There is no iron in the remaining 7% of the ore.) How many moles of Fe₂O₃ are present in this ore? How many kg of pure iron could be obtained from this sample of ore? Assume that the process has a 100% yield and that excess CO is available.
