The empirical formula of some condensation polymers __________. A) is the same as that of the monomer from which it is formed except that 2 H and 1O have been added B) is the same as that of the monomer from which it is formed except that 2 H and 1O have been subtracted C) is the same as that of the monomer from which it is formed D) is the same as that of the monomer from which it is formed except that 2 H and 1C have been added

Polymers are large molecules composed of simple units repeated many times. Thus, they often have relatively simple empirical formulas. Calculate the empirical formulas of the following polymers: (a) Lucite (Plexiglas); 59.9\% C, 8.06\% H, 32.0\% O (b) Saran; 24.8\% C, 2.0\% H, 73.1\% Cl (c) polyethylene; $86 \%$ C $, 14 \%$ H (d) polystyrene; $92.3 \%$ C $, 7.7 \% \mathrm{H}$ (e) Orlon; $67.9 \%$ C, $5.70 \%$ H, $26.4 \%$ N
