The diffusion coefficient of the molecule of hemoglobin in water is 6.3x10 –11 m^2 s^-1 at 20 °C. The viscosity of water at 20 °C is 1.002x10^–3 kg.m^-1 s^-1 and the specific volume of hemoglobin is 0.75 cm^3 g^-1. Assuming that the hemoglobin molecule is spherical and obeys Stokes' law; a) the radius of the molecule of hemoglobin, b) Find the molecular weight of hemoglobin?
