what is the mole ratio for iron from iron oxide

What mass of iron is formed when 240 g of iron(III) oxide ...

Mar 04, 2021· We can now figure out the moles of the iron: 240/160 = 1.5 mol. Then we need to find the ratio to make Fe. In the reaction, we know that 1 mole of Fe2O3 can make 2 moles of Fe. So 1.5 moles of Fe2O3 can make 3 moles of Fe. And then we need to find the mass of the Fe. 3×56=168 g. Hence 168g of the iron is made after the reaction.
