Two beakers are placed in a sealed box at 25 oC. One beaker contains 30.0 mL of a 0.050 M aqueous solution of a non-volatile nonelectrolyte. The other beaker contains 30.0 mL of a 0.035 M aqueous solution of NaCl. The water vapor from the two solutions reaches equilibrium.
(a) In which beaker does the solution level rise, and in which one does it fall?
(b) What are the volumes in the two beakers when equilibrium is attained, assuming ideal behavior?
