Pure iron can be extracted from iron ore, Fe203, from the reduction of carbon monoxide as shown by the following sequence of steps.
Step 1 c + O2 --> CO2
Step 2 CO2 + c --> 2CO
Step 3 Fe2O3 + 3CO --> 2Fe + 3CO2
In a single run, what is the maximum mass of iron that can be extracted from 60.0 g of carbon?
