Prepare a polymer solution by mixing 1 g of polystyrene with a molecular weight of 312000 g / mol and 1 g of polystyrene with a molecular weight of 364000 g / mol in 100 g of cyclohexane at T = 35 oC. Calculate the concentration fraction, c/ , is the average overlap concentration of the polymer mixture. where The temperature 0 for polystyrene in cyclohexane is 34.5 oc. The flexibility length is 1 nm and the monomer length is 0.25 nm. The density of cyclohexane is 0.78 g / cm3
