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.
