Can anyone help with AP Biology

which means that the bag needs to lose some of its sucrose in order to balance out the concentration gradient.-i am almost sure the bag will lose weight because if the pressure is zero but there is concentration difference so where ever the concentration of water is less water will move to that point.......
If the solute potential for a sucrose solution in a dialysis bag is -6.25 bars and it is immersed in a cup of sucrose solution having a solute potential of -3.25 bars and if the pressure potential inside and outside the bag is zero, will the bag gain or lose mass? Explain your answer.

-
The bag will lose mass because of the osmotic gradient. An osmotic gradient is the difference in concentration between two mediums. The sucrose concentration in the bag is higher than the one in the cup, which means that the bag needs to lose some of its sucrose in order to balance out the concentration gradient.
