    Answer;

    = 64561.95 g/mole

    Explanation;

    mass of Fe in 100g =.346g

    =.346 / 55.8452 moles

    = 0.0061957 moles

    These represent 4 moles of Fe in the molecule so moles of hemaglobin

    = 0.0061957/4

    = 0.0015489 moles

    these are in 100 g so mass of 1 mole = 100 / 0.0015489

    = 64561.95 g / mole

    molar mass of hemoglobin = 64561.95 g/mole
