Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Prutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin, a very large molecule that transports oxygen from the lungs to cells through the bloodstream. The chemical formula of hemoglobin is C2952H4664O832N812S8Fe4. Calculate the formula mass of hemoglobin.
