Teflon is a polymer composed of the tetrafluoroethylene monomer.  If you want to know how many monomers are in a particular sample of polymer, divide the mass of the polymer by the molecular weight of the monomer it is composed of.  In this case, a teflon monomer has a formula of C2F4, which has an approximate molecular weight of 100 (12*2 + 19*4).  If we divide 44489.5 by 100 we get 444.895.  So we round down to the nearest whole number to get 444.  So there are 444 teflon monomers in that particular sample.

Thank you for answering but I tried that before and it said the answer was wrong
