A 40-foot "fiberglass" boat hull weighs 2000 kg. Sixty percent of that is a fully cured crosslinked polyester resin (the remainder is the glass reinforcing fibers, pigment, fillers, etc.). What is the molecular weight of the polymer (in g/mol)? With a clear explination plases.

Explanation / Answer

length of curved crosslinked polyester = 0.6*40 = 24

molecular weight = 2000/24 = 8333.33gms/mol
