38. Solving a chemistry problem

311. The molar mass of the globular hemoglobin protein is 62300 g/mol, its diffusion coefficient in the will is 6.9*10-11 m2/s at 20 °C. Calculate the coefficient of friction f using the Einstein equation and the coefficient of friction of the equivalent sphere f0 using the Stokes equations, assuming a specific partial volume of 0.746 cm3/g and a viscosity of water of 1.00 cP. How much does the f/fo ratio differ from unity?
