The average concentration of chlordane, a chlorinated pesticide now banned in the United States, in the atmosphere above the Arctic circle in Norway was found to be 0.6 pg/m3 (Oehme et al., 19%). In this measure-ment, approximately 90% of this compound is present in the gas phase, the remainder is adsorbed to particles. For this problem, assume that all of the compound occurs in the gas phase, the humidity is negligibly low, and the average barometric pressure is 1 atm. Calculate the partial pressure of chlordane. The molecular formula for chlordane is C10Cl8H6.The average air temperature through the period of measurement was -5°C.
