Questions: If you can correctly explain to me at least 3 things wrong with this data table, you will receive 5 extra credit points.

To identify at least three issues with the provided data table, let's examine the information and calculations presented:

1. Calculation of Change in Volume:

   • The column labeled "Change in volume, \(V_{1}-V_{i}\) (mL)" seems to be incorrectly labeled. It should be \(V_{t} - V_{1}\) (mL) to represent the change in volume from initial to final. In the table, the change in volume is correctly calculated as 2 mL for Treatments A and B, but the label is misleading.

2. Percent Change in Volume Calculation:

   • The formula for "Percent change in volume" is incorrectly written as \((V_{1} V_{j} / V_{i}(\mathrm{~mL})\). The correct formula should be \(\frac{V_{t} - V_{1}}{V_{1}} \times 100\%\). For Treatments A and B, the percent change should be \(\frac{2}{90} \times 100\% \approx 2.22\%\), not 0.02\%.

3. Osmotic Conditions Mislabeling:

   • Treatment A is labeled as "Hypotonic," but both the solution in the dialysis tubing and the solution in the cup are 20% sucrose, which should be isotonic, not hypotonic. Similarly, Treatment B is labeled as "Hypotonic," but the solution in the tubing is 40% sucrose, and the solution in the cup is 20% sucrose, which should be hypertonic, not hypotonic.

In summary, the data table contains errors in the labeling of the change in volume, the calculation of percent change in volume, and the classification of osmotic conditions. These issues need to be corrected for the data to be accurately interpreted.
