b. 
Distilled water = (0,14 + 0,26 + 0,13) / 3 = 0,18
20% Sucrose solution = (-0,11 + (-0,26) + (-0,39)) / 3 = -0,25
40% Sucrose solution = (-0,53 + (-0,48) + (-0,59)) / 3 = -0,53

c. 
Distilled water : Mass of the potato increases because of water from distilled water diffuses into potatoes
20% and 40% sucrose solution : Mass of the potato decreases because of water from potato diffuses into sucrose solution. The higher the concentration of sucrose solution, the more water diffuses

d. Shelton used 3 pieces of potato so that the measurement results could be more valid
