Here it is:
A semipermeable sac, containing 4% NaCl, 9% glucose, and 10% albumin, is suspended in a solution with the following composition: 10% NaCl, 10% glucose, and 40% albumin. Assume the sac is peremable to all substances EXCEPT albumin. Using the key choices, insert the letter indicating the correct event in the answer blanks.
Key Choices
A) Moves into the sac B) Moves out of the sac C) Does not move
______1. Glucose
______2. Water
______3. Albumin
______4. NaCl
If anyone can help me on this it would be greatly appreciated.

A1 glucose moves in to equilibrate itself
B2 water moves out to lower the albumin % and get it closer to what's inside the sac
C3 it states that albumin cannot permeat the sac
A4 sodium moves in to raise the concentration and equilibrate it w/ what's outside the sac

1. Glucose will move into the sac by diffusion for the concentration of glucose is in the sac is lower than the concentration of glucose in the solution.
2. Water will move out of the sac by osmosis. This is because, there are more things in the solution, meaning that the water potential is less than the water potential in the sac.
3. Albumin will not move for the sac does not allow albumin to enter it.
4. Sodium Chloride will move into the sac by diffusion for the concentration of NaCl in the solution is higher than the sac.
Remember:
1. Diffusion: The movement of molecules from a region of higher concentration to a region of lower concentration down a concentration gradient through a semi-permeable membrane.
2. Osmosis: The movement of water molecules from a region of higher concentration to a region of lower concentraion down a concentration gradient through a semi permeable membrane.

Glucose-move into sac due to lower concentration inside of sac
Water-move out due to higher conc in sac
albumin-doesn't move because sac impermeable to albumin
NaCl--move into sac for same reason as glucose
