using the table below, create a graph for each of the following beakers.

1. Why should the bag in beaker 2 neither gain or lose weight ?

2. After completing the graph , compare the slopes of the lines for bags in beaker 3 & 4 . what correlation is there between the concentration gradient and the rate of osmosis?

3. compare the slopes of the lines for bag 1 and 3. why should the weight lost by one bag equal the weight gained by the other ?

using the table below, graph the information given. and answer the following questions.

1. why should the bag in beaker 2 neither gain or lose weight?

2. after completing the graph, compare the slopes of the lines for bags in beaker 3 & 4 . what correleation is there between the concentration gradient and the rate of osmosis?

3. compre the slopes of the lines for bag 1&3. why should the weight lost by one bag equal the weight gained by the other?
