Each of three closed (gas-tight) systems at 25°C contains 1.0 L of a 10 μmol/L chloroform
solution, but they are in equilibrium with different gas phases.
System I contains 1.0 L of gas with Ptot =1.0 atm,
System II contains 2.0 L of gas with Ptot = 1.0 atm, and
System III contains 1.0 L of gas with Ptot= 2.0 atm.
(a) What is the gas-phase concentration in each system?
(b) What is the total mass that was added to (and is still in) each system?
