A polymeric sample in which`30%`molecules have a molecules mass `20,000`,40%,`have `30,000`and the rest `30%`have`60,000`.The`(Mbar(n))`and(Mbar(w))`of this sample was:

Calaulate the average molecules mass of a polymer sample in which 30% molecules have a molecular mass of 20,000,40% have 30,000 ,and the rest 30% have 60,000

Calaulate the average molecules mass of a polymer sample in which 30% molecules have a molecular mass of 20,000,40% have 30,000 ,and the rest 30% have 60,000

Calculate the average molecular mass of a polymer sample in which 30% molecules have a molecular mass 20,000, 40% have 30,000, and rest have 60,000. Strategy: Work out number average molecular mass (overline(M_(n))) as well as weight average molecular mass (bar(M_(w)))

A polymer contains 30% molecules with molecular mass 20,000, 40% have 30,000 and rest have 60,000. Its bar(M)n is 36 xx 10^(x) . What is x.
