In a Blast Furnace, Elemental Iron Is Produced from a Mixture

In a blast furnace, elemental iron is produced from a mixture of coke (C) , iron ore (Fe₃O₄) , and other reactants. An important reaction sequence is 2C(s) + O₂(g) → 2CO(g)
Fe₃O₄(s) + 4CO(g) → 3Fe(l) + 4CO₂(g)
How many moles of iron can be formed in this sequence when 1.00 mol of carbon, as coke, is consumed?

A) 6.00 mol Fe
B) 3.00 mol Fe
C) 1.33 mol Fe
D) 1.25 mol Fe
E) 0.750 mol Fe
