(a)
Interpretation:
A portion of the polymer made from tetrafluoroethylene (Teflon) needs to be drawn.
Concept introduction:
A polymer is a long chain consists of large number of monomer units. In a polymer, the monomers are linked to each other in a continuous or repetitive manner. These monomer units are linked to each other either through the formation of peptide linkage, glycosidic linkage or by removal of any moiety such as a water molecule. Polyvinyl chloride, Bakelite and polystyrene are some of the examples of the

Interpretation:
The molar mass of Teflon molecule containing

These monomer units are linked to each other either through the formation of peptide linkage, glycosidic linkage or by removal of any moiety such as a water molecule. Polyvinyl chloride, Bakelite and polystyrene are some of the examples of the polymers. Tetrafluoroethylene polymer (Teflon) consists of large number of monomer units of 1,1,2,2-tetrafloroethylene in it.
(c)
Interpretation:
The mass percent of C and F in the Teflon polymer needs to be determined.
Concept introduction:
Mass percent of an atom present in the sample can be determined by dividing mass of atom present in the monomer to the overall mass of the monomer units and multiplying the overall result with 100%.
For example, the mass percent of x g of an atom present in the y g of monomer units can be determined as:
