The molar mass of human hemoglobin is 4500 g / mol. Calculate the mass fraction of iron in hemoglobin, assuming that one hemoglobin molecule contains 5 iron atoms.
The atomic mass of iron is 56 amu, 5 of its atoms will weigh 5 * 56 = 280 amu in a hemoglobin molecule, the proportion of Fe in the molar mass of protein is 280: 4500 = 0.0622, or in percent, then 0.0622 * 100% = 6.22%, this will be the mass fraction of iron in hemoglobin.
