#### Answer

The water should flow from the NaCl solution to the KNO3 solution.

#### Work Step by Step

The number of moles of NaCl: $5.85\ g\div 58.44\ g/mol=0.1\ mol$ The number of moles of KNO3: $8.88\ g\div 101.10\ g/mol=0.088\ mol$ Since both solutions are dissolved in the same volume of water, at the same temperature, are very soluble in water (complete dissociation) and release the same number of ions per compound (i =2 for each of them), the water should flow from the NaCl solution to the KNO3 solution.
