43. Solving a chemistry problem

4. Svedberg, when centrifuging blood hemoglobin for 39 hours (to achieve sedimentation equilibrium), found that the concentrations of the dispersed phase at distances from the ultracentrifuge rotation axis of 4.61 and 4.56 cm were equal to 1.061 and 0.930%, respectively. The number of revolutions of the centrifuge is 8700 rpm. The density of the medium at 293 K is 1.008 g/cm3. And hemoglobin is 1.335 g/cm3. What is the molecular weight of hemoglobin?
