a report on an experiment to determine the percentage change in mass of the potato chips due to the  I had done a test for sodium chloride in potato chips with mohr method (done according nielson food analysis lab manual) which required to use 01m agno3, after standardized the agno3 with 01gkcl (which dissolve in 25ml dd water) using 137ml of agno3, i counted and get 00974m agno3, which approximate 01m agno3 then, it required to use 5 g of potato chips which added with 95ml boiling dd .

Biology lab report: osmosis done by: seonlim lee (lynn) g10b purpose -to find the isotonic point of the potato -to determine the weight changes after submerging the potato in different concentration of salt water for 20 minutes. Determine the mass difference, the percent change in mass and the class average percent change in mass graph the increase and decrease in mass of the potato cores according to the molarity of the solutions they were placed in on graph 12. Complete set of diffusion/osmosis labs of sucrose with a water potential ____ to the potato tissue water potential change in the mass because it was what was .

We were able to experiment and discover that the potato slices immersed in the lower glucose solutions, yielded to a higher mass than the ones immersed in the higher glucose solution due to the particles moving from an area of higher concentration to a lower one. In this specific experiment, there are specific factors that can affect the rate of osmosis affects the length and mass of the potato this is due to the . Experiment-13: amount of fat in potato chips laboratory report#13: amount of fat in potato chips 7 % of lipid in potato chips = (mass of lipid extracted . Why do you calculate the percent change in mass rather than simply using the change in mass report abuse comment add a comment by stating the .

Data: percent change in potato cylinder mass graph of %change in potato cores vs sucrose molarity, the point where line crosses the x-axis is the molar concentration of sucrose with a water potential that is equal to the potato tissue water potential. In this experiment we need six solutions: 0g per 100ml, which is just pure water, and 1 to 5 g/ 100ml in 1 g increments once the solutions are ready, pour them in to immerse the potato strips . Initial mass of potato= 006×100/170=353%percentage change in mass of the potato cylinder in experiment 2x 100∆mass=initial mass of potato= 002×100/191=105%in order to calculate the change in the mass of each potato cylinder wemust calculate the change in percentage of the potato cylinders to find theaverage change in mass for the .

The whole for this experiment was basically to determine if my hypothesis, which is “if potato cores are submerged into different solutions with varying water concentration, then the mass of the cores will change depending on the amount of water present,” can be proven. - investigating the effects of sucrose concentration on the mass of potato chips the aim of my experiment is to investigate the effect of varying the concentration of sucrose on a potato chip i aim to observe the change in mass, and i hope to view what happens to the chips as the concentration increases, and i hope to see the effect that . Figure 1: change in mass of potato (g) due to water gain/loss as a function of salt concentration 3 when completed, use a ruler to draw a straight line of best fit through your six data points, or use the computer to graph your data and calculate the line of best fit.

We will write a custom essay sample on potato osmolarity lab determine mass of potato cores using a laboratory balance on my graph the percentage change in . 6 determine the molar concentration of the potato cores this would be the sucrose molarity in which the mass of the potato core does not change. Determining the unknown concentration of a sugar solution through osmosis we measured the change in mass of the to find the percent mass we took the mass of .

Knowing the mass of solute dissolved in the standard, a proportion was set up to determine the mass of solute in the unknown (in the dialysis tubing), because only the water could not penetrate the walls of the tubing using this mass and information about the mass change of the two solutions during osmosis (water movement), the initial solute . Alternatively5 0 2)ath average percentage change in mass and length of potato strips at each nacl concentration average percentage change in mass and length of potato strips at each nacl concentration 30 20 average percentage change/% 10 0 0 -10 -20 r² = 0 the mass and the length exemplified after an approximate 24-hour period increases . We will write a custom essay sample on experiment to investigate osmosis in percentage change in mass of the potato tubers the potato chips were dried in the .

  • Our hypothesis of “if potatoes are placed in solutions of increasing molarity of glucose then the potato’s mass change will decrease and become negative because osmosis will cause the water molecules to move to the area with less solutes (glucose)” was supported in our experiment we found .
  • I need results for the experiment of osmosis by only changing the concentration outside the potato but using the values volume of the total solution 20cm cubed the potato just using a normal cork borer cutting the pieces of.

In some cases it is correct because the concentration is higher and the mass of the potato is lower, but in other cases the mass of the potato gets higher, which i did not predict for example, on the 1st experiment at 2 and 4 concentrations the mass of the potato goes up and the same happens on the 2nd experiment at the 6% concentration. What is the independent variable of this experiment the percentage change in mass of the potato chips start studying biology osmosis in potatoes learn . To determine concentration of overall solute in potato cells, wait until the potato cylinders reach equilibrium and measure the change in weight since the solute concentration of outside solution is known, one can determine the concentration of solute in potato cells by the change in weight after it reaches equilibrium.
