DESCRIPTION
137. Solving a chemistry problem
The diffusion coefficient of cane sugar in water at 290 K is 3.9 • 10-5 m2 / day. The viscosity of water is 1.083 • 10-3 N • s / m2. Calculate the radius of the molecule (in m) and the molar mass of the organic matter. The density of cane sugar is 1.587 • 103 kg / m3. Compare the resulting molar mass with the theoretical value (M = 342
g / mol) For the calculation, we use the Einstein equation:
