i keep getting D but the answer is C

mm = 75
therefore 1000 monomer units is 75*1000 = 75,000

but you have to factor in the extra water that will be produced (condensation polymer!!!)
mm(water) = mm(H2O) = 18
therefore you have 1000 water molecules made (mm = 18,000)

hence, total molar mass = 75,000 - 18,000 = 57,000 = 5.7*10^4

you did this on the other condensation polymer too
