Sarah Henthorn Lab Partners: Matt Sandoz, Laura Soileau Change in Mass of Potato in Sucrose Solutions This lab experiment consisted of potatoes which were cut into small pieces and then cleaned, the potatoes were then put into sucrose solutions to see how the changes in molarity would affect the mass of the pieces of potato. We first weighed the potatoes then put 4cm divided segments into cups with sucrose concentration of 0M, 1M, 2M, 3M, 4M, and 5M. The potatoes were then incubated in beakers with the sucrose solutions for one hour, and swirled every ten minutes. The masses increased and also decreased at the end of the hour. The general trend for the masses compared to the sucrose concentration was that the lower the molarity of sucrose, the greater the change in mass. The higher the molarity of sucrose, the mass of potato decreases. The results are listed on the graph at the bottom of the next page. These results explain how the dependent variable, which is the sucrose,

The second graph shows the change in mass of potato in sucrose solutions. The third data chart shows the amount of potato in grams before submerged in sucrose and after the experiment was over. The percent change in mass is relatively similar to the change in mass throughout the whole experiment for each molarity of sucrose. However, this trend is not the same for 0 Molarity; it is somewhat smaller. potato experiment Sucrose Concentration 0 M 1 M 2 M 3 M 4 M 5 M initial mass (g) 3.6 7.3 3.7 6.9 8.6 6.7 final mass (g) 4.1 8.1 4 7 8.2 5.7 change in mass (g) 0.5 0.8 0.3 0.1-0.4-1 % change in mass 13.8888 9 10.958 9 8.10810 8 1.44927 5-4.6511 6-14.925 4 0 M 1 M 2 M 3 M 4 M 5 M 0.5 0.8 0.3 0.1-0.4-1 0 M 1 M 2 M 3 M 4 M 5 M 13.8888 9 10.958 9 8.10810 8 1.44927 5-4.6511 6-14.925 4...
