A0.21 m3 (55 gal) drum contains 100 l of a mixture of several degreasing solvents in water. the concentration of trichloroethylene in the headspace (gas phase) above the water was measured to be 0.00301 atm. the henry’s constant for trichloroethylene is 0.00985 atm·m3·mol-1 at 25°c. what is the concentration of trichloro-ethylene in the water in units of molarity? (assume that the temperature of the solution is 25°c.)
