I am working with Polyethylene glycol PEG of different mol wt (200 to 3400). I am intresting in knowing about how to calculate its

 a  Radius of gyration

 b  Contour lenght

 c  end to end distance

 Please let me know if there is some common formula which is applicable to find the above mentioned parameters for all the mol wt fall in this range (200-3400)

               ie Rg =

   So i need help in this regard asap
