Homework Help: OSMOSIS what do you expect to happen!

    OSMOSIS!!! what do you expect to happen!

    Hey guys can someone help me with the osmosis scenarios and rank them in order of the most mass gained and also write a good definition of what osmosis is thanks.

    thanks

    first of all i have the following solutions
    i have 5% sucrose in dialysis tube in distilled water - cup 1
    i have 10% sucrose in dialysis tube in distilled water - cup 2
    i have 20% sucrose in dialysis tube in distilled water - cup 3
    i have 20% sucrose in (0.9% nacl solution - cup 4
    i have 5% nacl in distilled water - cup 5

    my definition of osmosis is what it think is the net movement of water molecules from area of high concentration to low concentration.

    normally i would expect the higher concentration in the dialysis tube the more it will gain in mass but i got confused with the 5% nacl in distilled water and 20% sucrose in 0.9% nacl, i dont know which is more concentrated but would i assume 20% sucrose in 0.9% nacl isotonic??? please rate the order you guys think from less increasing mass - most increasing mass i will have a shot and chose.

    THE ORDER from 1 (lowest increasing mass ) to 5 ( most increasing mass)

    1. cup 4
    2. cup 1
    3. cup 2
    4 cup 5
    5. cup 3

    thats my guess anyone else want to give a try????
