Answer on Other Chemistry Question for Emily Connor
What is the molecular weight of the acrylic polymer
The weight average molecular weight is a way of describing the molecular weight of a polymer. Polymer molecules, even if of the same type, come in different sizes (chain lengths, for linear polymers), so we have to take an average of some kind. For the weight average molecular weight, this is calculated by
Mw = ЕiNiMi^2 / ЕiNiMi
where Ni is the number of molecules of molecular weight Mi. To calculate the molecular weight, you need to know the number of acrylic molecules.
