1. The chemical equation for the propylene monomer is CH = CH I CH3 a) Bearing in mind that the masses of 1 atom of hydrogen H and carbon C are respectively 1 a.m.u. and 12 a.m.u. (atomic mass units), calculate the relative molecular mass (RMM) of 1 molecule of polypropylene PP where the degree of polymerization n = 15 000. b) If you are given a sample of polypropylene as above of total mass 10 g, where all the molecules have the same degree of polymerization n = 15 000, is the number average molar mass M_larger than, equal to, or smaller than the weight average molar mass Mw?
