Consider the metalloprotein hemoglobin, which has four heme groups each coordinated to a single iron ion. Suppose that ferrous iron in the heme group of hemoglobin is oxidized to ferric state by reacting with hydrogen peroxide. Calculate the number of hydrogen peroxide molecules needed to oxidize all the iron ions of hemoglobin in a human body that has a total of 5 liters of blood, assuming the concentration of hemoglobin in blood is 15 grams per liter.
