How many moles of iron(III)oxide are required to completely react with 1.40 10²² atoms of carbon? Fe₂O₃ + 3C 2Fe + 3CO

Question

Quizplus · Accepted Answer

From the balanced equation, we see that 2 moles of Fe2O3 reacts with 3 moles of C. Therefore, the number of moles of Fe2O3 required can be calculated as follows:
1.40 x 10^23 atoms of C x (1 mole of C/6.022 x 10^23 atoms of C) x (2 moles of Fe2O3/3 moles of C) = 0.00775 moles of Fe2O3
Therefore, the best choice is B.
