ABS is a tough plastic composed of three smaller units called monomers: A= acrylonitrile(C3H3N), B= butadiene (C4H6), and S= styrene (C8H8). A.) A sample of ABS plastic contains 8.80% N by mass. It takes 0.605 g Br2 to react completely with a 1.20 g sample of ABS plastic (Br2 reacts 1:1 molar ratio with butadiene and nothing else). What are the mass percents of acrylonitrile and butadiene in this plastic?    B.) What are the relative numbers of monomers of A,B and S in this plastic?
