Calculate the change in mass and the percentage change in mass of each set of potato pieces.

UFP Biology for Life Sciences:

Calculate the change in mass and the percentage change in mass of each set of potato pieces.

13. Plot percentage change in mass (y-axis) against concentration of Sucrose solution (x-
axis).

14. Calculate the percentage change in mass using the formula below:
% change in mass = final mass – initial mass x 100%

14. Where there is no net gain or loss in mass, CELL is equal to BATHING SOLUTION. From your graph read the molarity of sucrose where the percentage mass change is zero.

15. From the table below, find the water potential of a sucrose solution of that molarity
