Two beakers are placed in a sealed box at \(25^{\circ} \mathrm{C}\). One beaker
contains \(30.0 \mathrm{~mL}\) of a \(0.050 \mathrm{M}\) aqueous solution of a
nonvolatile nonelectrolyte. The other beaker contains \(30.0 \mathrm{~mL}\) of a
\(0.035 \mathrm{M}\) aqueous solution of \(\mathrm{NaCl}\). 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?
