To get the amount of amus in Fe2O3 which is iron III oxide, we simply multiply the amus of iron by 2 (56 x 2 = 112) and the amus of oxygen by 3 (16 x 3 = 48) and add them to get 160amus. This is because there are two iron atoms and three oxygen atoms in the iron III oxide molecule. Hope that helps!So we're going to need 0.833 moles of molecular oxygen. And then I just multiply that times the molar mass of molecular oxygen. So, times 32.00 grams per mole of molecular oxygen. 0.833 times 32 is equal to that. If you go three significant figures, it's 26.7. 26.7 grams of oxygen, of molecular oxygen.The balanced equation must now be used to convert moles of Fe (s) to moles of H 2 (g). Remember that the balanced equation's coefficients state the stoichiometric factor or mole ratio of reactants and products. 3.74 x 10 -5 mol Fe (s) ( 1mol H 2 (g)/ 1mol Fe (s)) = 3.74 x 10 -5 mol H 2 (g) Step 5: Check units.Expert Answer.
