Question: ABS plastic is a tough hard plastic used in applications

ABS plastic is a tough, hard plastic used in applications requiring shock resistance. The polymer consists of three monomer units: acrylonitrile (C3H3N), butadiene (C4H6, and styrene (C8H8).
a. Draw two repeating units of ABS plastic assuming the three monomer units react in a 1:1:1 mole ratio
and react in the same order as the monomers previ¬ously listed.
b. A sample of ABS plastic contains 8.80% N by mass. It rook 0.605 g of Br2 to react completely with a 1.20-g sample of ABS plastic. What is the percent by mass of acrylonitrile, butadiene, and styrene in this polymer sample?
c. ABS plastic does not react in a 1:1:1 mole ratio between the three monomer units. Using the results from part b, determine the relative numbers of the monomer units in this sample of ABS plastic.
