[10 points] You are performing a step-growth reaction of toluidine diisocyanate (TDI, 189.17g/mol) and polycaprolactone 1k(PCL1k,1250g/mol) diol in order to make a semi-crystalline polyurethane. Your mentor decides last minute that you should use hexamethylene diisocyanate (HDI, 168.19g/mol) instead to help both with flexibility and biocompatibility. You calculated the weights required for TDI and PCL1k so you would have a stoichiometric balance of 1 . If you accidentally use your calculated mass for HDI, what is the max average number of monomer residues per molecule you would be able to achieve
