A 0.36 m3 drum contains 140 L of a dilute solution of trichloroethylene (TCE) in water. The concentration of TCE in the headspace (gas phase) above the water was measured to be 0.0221 atm. Henry's constant for TCE is 0.00985 atm-m/mele mole/ (atm m3) at 25C. There are no other constituents in the water

 

a) Calculate the [Molar] conc. of trichloroethylene in this solution 

 

 

b) Calculate the TCE concentration in units of mole fraction,

 

 

c) Calculate the TCE concentration in units of parts per billion (ppb).
