lab benches wipe potato are discarded and not left in your preparation area. Results: Record your data from the experiment in Table 2 below: Table 2: Mass of potato cores in different concentrations of over time solution Concentration of Mass of Potato Cores (g) at Different Times Solution (M) 0 (min) 10 (min) 20 (min) 30 (min) 40 (min) 50 (min) 60 (min) 0.3 0.5 129 Lab Exercise 3C Table 3: Cumulative Percent Change in Mass at Diferent Times Cumulative Percent Change in Mass Concentration of 0 (min) 10 (min) 20 (min) 30 (min) 40 (min) 50 (min) 60 (min) Solution (M) 0.1 0.3 0.5 1 to complete the following:

Explanation / Answer

mass difference = final mass - initial mass.

% change in mass = [(final mass - initial mass) / initial mass] *100

for 0 min readings all are zero.

for 10 min reading - 0 M = 0.

0.1 M = (0.1/4.3) *100 = 2.32%

0.3 M = 0

0.5 M = 0

1 M = (-0.1/3.8)*100 = -2.63%

for 20 min reading - 0 M = (0.2/5)*100 = 4%

0.1 M = (0.2/4.3) *100 = 4.65%

0.3 M = 0

0.5 M = (-0.1/4.3)*100 = -2.32%

1 M = (-0.3/3.8)*100 = -7.89%

for 30 min reading - 0 M = (0.1/5)*100 = 2%

0.1 M = (0.2/4.3) *100 = 4.65%

0.3 M = 0

0.5 M = (-0.2/4.3) *100 = -4.65%

1 M = (-0.5/3.8)*100 = -13.15%
