The system below contains a semipermiable membrane. The volume of the chambers are 50.0 mL for the water and 45.0 mL for the CaCl2 solution. (solution density = 1.05 g/mL) An added pressure, P, of 0.22 atm is applied to the piston to maintain the volumes occupied by the water and salty water. What is the concentration (in mol/L) of CaCl2 in the water?
