[Avogadro]

A sample of PVC has an average molecular weight of 7.2X10^4. What is the average number of monomer units in this sample.

I'm not sure what to do. Can someone help? Thanks heaps!

7.2 x 10^4 divided by the molecular weight of a single monomer which is 62.498

why don't you multiply by 6.022x20^23

I see, to be honest, I haven't come across a question like this but I think you're right.
