Solved: Polychlorinated biphenyls (PCBs) have been used
Chapter , Problem 98(choose chapter or problem)
Polychlorinated biphenyls (PCBs) have been used extensivelyas dielectric materials in electrical transformers. Because PCBshave been shown to be potentially harmful, analysis for theirpresence in the environment has become very important. PCBsare manufactured according to the following generic reaction:This reaction results in a mixture of PCB products. The mixtureis analyzed by decomposing the PCBs and then precipitating theresulting Cl_ as AgCl.a. Develop a general equation that relates the average value ofn to the mass of a given mixture of PCBs and the mass ofAgCl produced.b. A 0.1947-g sample of a commercial PCB yielded 0.4791 gof AgCl. What is the average value of n for this sample?
