6. Assume you have a monomer and a solvent of almost equal size. (15 points) a. Estimate, using a simple lattice model, the number of distinguishable arrangements for a solution of 0.25 mole of the monomer in 7.5 moles of the solvent. b. What would be the entropy of mixing the monomer and solvent? c. If the monomer is polymerized to chains of degree of polymerization 120 , what would be the entropy of mixing the polymer with the same 7.5 moles of solvent
