    Molar mass of hemoglobin is 64380.4 g/mol

    Explanation:

    Percentage of Fe calculated from the equation

    %Fe = 4*molar mass of Fe/molar mass of hemoglobin. (4 because hemoglobin contain 4 Fe atoms)

    Molar mass of hemoglobin is = 4*molar mass of Fe / % Fe

    =4*55.85/.00347

    =64380.4 g/mol.
