Answer:
20 moles of Iron are needed
Explanation:
In 1 mole of Iron (III) oxide, Fe₂O₃, there are 2 moles of Iron, Fe. The equation that we can write is:
2 moles Fe = 1 mole Fe₂O₃
To find the moles of iron that are needed to produce 10 moles of Fe₂O₃ we must use this equation as follows:
10 moles of Fe₂O₃ * (2 moles Fe / 1mole Fe₂O₃) =
20 moles of Iron are needed
