913. The diffusion coefficient of maltose in water at T= 291 K is 3.92·10-5 m2/day. The viscosity of water is 1.06•10-3 N•s/m2. Calculate the radius of the molecule (in m) and the molar mass of the organic matter. The density of maltose is 1.540×103 kg/m3. Compare the obtained value of the molar mass with the theoretical one (M = 342 g/mol).
