In a polymer sample, `30%` of molecules have a molecualr mass of `20,000, 40%` have 30,000 and the rest 60,000. What is the weight average molecular mass of the polymer?

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)))

In a polymer sample 30% molecules have a molecular mass 20,000 , 40% have molecular mass 30,000 and rest have 60,000 .The number average molecular mass is x times10^(4) then x is

A sample of polymer contains 30% molecules with a molecular mass 20,000 , 40% with molecular mass 30,000 and 30 % with 60,000 ." .What is the number average molecular mass of the polymer?

In a polymer sample, 30% molecules have molecular mass 20000, 40% have molecular mass 30000 and the rest 30% have 60000. Calculate their number average and mass average molecular masses.

bar(M)_(n) of a polymer containing 30% molecules with molecular mass 20,000, 40% have the rest have 60,000 is

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:
