Below is a simple set of weights obtained while immersing potato slices in various sugаr solutions over 60 minutes. Time OM sucrose 0.4M sucrose 0.6M sucrose (min) 0.8 M sucrose 1.0M sucrose
(min)
0 4.36 g 4.59 g 4.7g 4.5 g 5.0 g
30 4.5 g 4.3 g 4.4 g 4.1 g 4.6 g
60 4.68 4.28 4.0 g 3.7 g 4.08
For each solution, calculate the rate of weight change over this 60-minute period.
Using the osmosis data in the question above, determine the percent weight change for each sucrose solution.
0.0M sucrose = %
0.4M sucrose = %
0.6M sucrose = %
0.8M sucrose = %
1.0M sucrose = %

Explanation:

The rate of weight change can be determined by using the formula:

weight change = weight at the final time - weight at the initial time.

Molarity                     Weight change

0.0M sucrose  →        (4.68 - 4.36)  =  0.32  g/min

0.4 M sucrose →         (4.28 - 4.59) =  - 0.31  g/min

0.6 M sucrose →         (4.0 - 4.7)      =  - 0.7   g/min

0.8 M sucrose →         (3.7 - 4.5)      = - 0.8    g/min

1.0 M sucrose  →         (4.08 - 5.0)   = - 0.92  g/min

Percent weight change =

Now;

Molarity                     Weight change

0.0M sucrose  →             =   6.8 %

0.4 M sucrose →              = 8.4 %

0.6 M sucrose →               = 14.8 %

0.8 M sucrose →               = 17 %

1.0 M sucrose  →                = 18.4%

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
