At 0:39 you say "So what's the molecular weight of the monomer... molecular weight of the monomer..." I think you mean to say polymer instead of monomer correct? Maybe add a caption to make people aware of that error.

In which vid did you explain how to find the molecular weight of repeat unit?

as for my concern the formula fo DP = AVERAGE WEIGHT OF MOLECULAR (Mn) / MW OF MONOMER

What is the molecular length (micrometer) of a PE (C2H4) molecule consisting of 1800 (regular PE) and 250,000 (UHMWPE) monomers, respectively? Using the average diameter of a carbon atom, 0.16 nm, for calculation and assuming no overlapping between carbon atoms How would I figure out this one?

did u ever figure it out?

Find the total number of carbon atoms in the chain and multiply it by the diameter of carbon. Therefore the max theoretical length would be 1800*2*0.16 nm and 250000*2*0.16nm - i think.
