Answer: Water will move throung the bag, but this flow is the same into and out because the solute concentration is the same.
Even if the compounds are different, the amount of moles per liter is the same (0,2 mol/L). So it is possible to say that the bag is in a isotonic medium in which water flows at the same rate into and out of the bag keeping it with the same amount of water, which is called a dynamic equilibrium
