Volume Fraction of a Polymer

  1. Jun 6, 2015 #1
    I have a tutorial question that I'm not too sure of.

    The question states:

    Calculate the volume fraction Φ for a polymer solution of concentration C (given in g/L) and hydrodynamic radius R?

    The answer was given as

    Could someone explain how V total was gotten?

    Am I right in assuming the Volume of Polymer would be the volume of a the sphere multiplied by the number of polymers?

    [Could this be a potential error in the solutions? In my notebook I have (C / NM)*sphere Volume]
