4.90 Iron metal can be refined (rom the mineral hematite (Fe 2 O 3 ). One way of converting the mineral to iron is to react it with carbon monoxide, as shown below: Fe 2 O 3 + 3 CO → 2 Fe + 3 CO 2 Because the hematite is obtained from various ores, it is usually not in a pure form. Suppose an iron manufacturer has 2.00 X 10 5 kg of ore available, and the ore is 93% Fe 2 O 3 by mass. (There is no iron in the remaining 7% of the ore.) How many moles of Fe 2 O 3 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.

Because the hematite is obtained from various ores, it is usually not in a pure form. Suppose an iron manufacturer has 2.00 X 105 kg 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 Fe2O3are 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.
