Viscosity of sugar

  1. Feb 17, 2009 #1
    hi, this is the first time i learn about viscosity, but I don't know where to start with this question:
    At 18.5°C, the viscosity of 1 wt% aqueous sugar solution is 1.025 times higher than the viscosity of pure water. At the same temperature, the diffusion coefficient of the sugar molecules is 3.82×10-6cm2/sec and the molecular weight is 342.30. Determine the Avogadro number and the size of the sugar molecule.
    if you know any good website, plz show me :)
