Of fresh green paper strips were placod in sucrose solutions of varying concentrations to investigato the
changes in mass. The striper, each measuring (4 x 0.5 cm were to cut from the walls the truit at
total of 18 strips were out and the mass of each dortorminod Three stripes were then placed
in the following solutions: 0. 20.4, 0.6,0.8 $ to lomol Idms, rospectively theree were placed
in distilled worler. All were lett for 30min and then removed & rewoiched The mean
mous of each group of three strips was calculanted. The results were recorded on a table shown below
