Question
2Fe2O3 + 3C 4Fe + 300,
When 9.20 moles of carbon dioxide are produced from the reaction above, how many moles of Iron(III) Oxide must have been present before the reaction took place?
Answer:
3.1 moles of Iron(III) Oxide
Explanation:
The equation of the reduction of iron III oxide using carbon is shown;
Fe2O3 + 3CO → 2Fe + 3CO2
From the reaction equation;
1 mole of Iron(III) Oxide yielded 3 moles of carbon dioxide
x moles of Iron(III) Oxide will yield 9.20 moles of carbon dioxide
x = 9.2 moles * 1 mole/3 moles
x = 3.1 moles of Iron(III) Oxide
