ABS plastic is a tough, hard plastic utilized in applications requiring shock resistance. The polymer consists of three monomer units: acrylonitrile (C3H3N), butadiene(C4H6), and styrene(C8H8).
(a) A sample of ABS plastic contains 8.80% N by mass. It took 0.605 g of Br2 to react fully with a1.20 g sample of ABS plastic. Bromine reacts 1:1 (by moles) with the butadiene molecules in the polymer and nothing else. Explain what is the percent by mass of acrylonitrile and butadiene in this polymer?
b) Explain what are the relative numbers of each of the monomer units in this polymer? Give the ratio of acrylonitrile: butadiene: styrene. Utilize the lowest possible coefficients.)
