A 0.21 m3 drum contains 100 L of a mixture of several degreasing solvents in water. The concentration of trichoroethylene in the headspace (gas phase) above the water was measured to be 0.00301 atm. The Henry's constant for trichoroethylene is 0.00985 atm m3 mol-1 at 25degrees C. What is the concentration of trichoroethylene in the water in units of molarity? (Asume that the temperature of the solution is 25deg. C
