Calculate the area of the rug in square yard (yd2):
1 yd = 3 ft
A = 24.5555 yd2
Calculate the mass of Acrilan® in the rug:
1 oz = 28.3495 g
mass Acrilan® = 20884.1 g
Calculate the mass of HCN:
Hydrogen cyanide, HCN, is a poisonous gas. The lethal dose is approximately 310 mg HCN per kilogram of air when inhaled.
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 measures 13 x 17 ft and contains 30 oz of HCN of Acrilan® fibers per square yard of carpet. If the rug burns, will a lethal dose of HCN be generated in the room? Assume that the yield of HCN from the fibers is 20% and that the carpet is 50% consumed.
