Answer
$m= 100.02 g/mol$
Work Step by Step
Required:
Compute repeat unit molecular weights for polytetrafluoroethylene.
Solution:
From Table 14.3, each repeat unit consists of 2 carbons and 4 fluorines. $A_{C}$ and $A_{F}$ represent the atomic weights of carbon and fluorine, respectively.
$m = 2(A_{C}) + 4(A_{F}) = 2(12.011 g/mol) + 4(19.00 g/mol) = 100.02 g/mol$
