Hcn forms when synthetic fibers containing orlon® or acrilan® burn. acrilan® has an empirical formula of ch2chcn, so hcn is 50.9% of the formula by mass. a rug in the laboratory measures 3.70 × 4.20 m and contains 30.0 oz of acrilan® fibers per square yard of carpet. if the rug burns, what mass of hcn will be generated in the room? assume that the yield of hcn from the fibers is 20.0% and that the carpet is 42.0 % consumed.
