Title: Soft matter & Polymers
Post by: iliannak on May 22, 2020, 04:21:07 AM
In the solvent hexane, the average end-to-end distance of a 7 kDa molecular weight poly(ethylene glycol) polymer chain is 3.65 nm and the average end-to-end distance of a 56 kDa molecular weight poly(ethylene glycol) polymer chain is 7.30 nm. By calculation, show whether hexane is a good, poor or theta solvent for poly(ethylene glycol).

Personally, my fee for answering homework questions is £100 per question. ;D

Seriously, I suspect you won't get an answer unless you show us what you've tried and exactly what you are having a problem with.
