Make sure you use the proper variables.

Explanation / Answer

* The bags (0.0 M) and (0.2 M) are less concentrated (hypotonic) than 0.4 M sucrose. They will gain water.

* There is no net movement of solvent for the bag with 0.4 M sucrose (it is isotonic with the contents of bag)

* The bags (0.6 M0, (0.8 M), and (1.0 M) are hypertonic, and will lose water.
