A laboratory assistant prepared solutions of 0.2 M, 0.4 M, 0.6 M, and 0.8 M sucrose but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. To determine the concentrations of each solution, the assistant filled four dialysis tubes with the four different solutions, took their initial masses, and placed each tube into distilled water overnight. The next day, the masses of each dialysis tube again were recorded. Using the data below, determine which concentration of sucrose solution is in each flask.

Answer:

To determine the flask on basis of the molarity or concentration of the solutions, an individual should design an experiment with the help of using water and dialysis tubes. Dialysis tubes up should be filled with pure water, then seal or closed them from both ends.

Measure the weight and note the mass of each tube, student should stick label the cups with the solutions. Weighing the solutions after leaving them for 8 to 10 hours. The tubes would lose weight as water leave the tube when placed in the solutions due to the principle of diffusion- movement.

The measure of the chemical constituents of the specific solute in a solution is called molar concentration.

For the determination of the flasks based on the molarity and concentration, the experiment should be designed based on dialysis tubes and water.

The dialysis tubes should be filled with pure water and both the ends of the tubes should be sealed.

The tubes should be measured and marked. Place the tubes into the solutions and after leaving them overnight weigh them again.

The weight of the tubes will decrease because of the flow of water.

Therefore, due to diffusion movement, the tubes will lose weight and the concentration of the flasks can be determined.
