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
