Henry's law is important in environmental chemistry, where it predicts the distribution of poliutants between water and the atriosphere. The zwalrocarbon propylbenzene (C9H12) emilted in watewater streams, for example, can pass into the air, where it is degraded by processes induced by light from the sun. The Henry's lew constant for propylbenzene in water at 25 .C is 566 atm, when the following form of the law is used: Propythemene=KpropyltenreneXpropylbenzene Calculate the partial prespure of provylbenzene vopor in equilibriam with a solution of 1.130 of propylbenrene per 1060 Lof water.
