Answer:
0.16 moles of Carbon
Explanation:
The balanced reaction equation:
[tex]2Fe_{2}O_{3}[/tex] + [tex]3C[/tex] → [tex]4Fe[/tex] + [tex]3CO_{2}[/tex]↑
The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)
i.e 3 moles of C produces 4 moles of Fe.
If 1 mole of Fe - 55.8g of Fe
? moles - 11.6g of Fe
= [tex]\frac{11.6}{55.8}[/tex] = 0.208 moles
But 3 moles of C - 4 moles of Fe
? moles of C - 0.208 moles of Fe
= [tex]\frac{3 *0.208}{4}[/tex] = 0.16 moles of carbon.
I hope this explanation was clear and useful.
