Please help - AP Bio Water potential is the tendency of water to move from one place to another. Pumpkin cores were placed in sucrose solutions at 22°C and normal atmospheric pressure. The following data were gathered.

Individual Data for Pumpkin Cores

Contents in beakers Initial mass Final mass Percentage

change in mass

Water 29.15 32.12

0.2 M sucrose 28.45 29.41

0.4 M sucrose 30.92 29.84

0.6 M sucrose 29.25 27.14

0.8 M sucrose 32.09 28.54

1.0 M sucrose 31.67 27.58

a) Complete the above table

b) Graph the percentage change in mass. Label both the x and y axes.

c) Using the graph, determine the molar concentration of the pumpkin cores and explain how it is related to pressure potential.
