The balanced chemical equation for this reaction is 4 Fe + 3 O 2 --> 2 Fe2O3 Now from the balanced chemical equation we see There are 4 moles of Fe. We also see there are 2 moles of Fe2O3. So their ratio is Fe : Fe2O3 = 4 : 2. Simplifying by diving by 2, we get Fe : Fe2O3 = 2 : 1

Most analytical methods only count metals, but report metal oxides. This is why you have a “total” – it’s reported as if all Fe was FeO or as Fe2O3. So, assuming you did not specifically measure FeO and Fe2O3 (using titration, Mossbauer, etc), you will never know. green valley ranch las vegas theatre
