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 th

e 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.

To establish the type of flask based on the molarity or concentration of the solutions, one should set up an experiment using dialysis tubes filled with distilled water, securing both ends of the tubes tightly. The mass of each tube should be noted, and labels should be affixed to the cups holding the solutions. After allowing the solutions to sit for 8 to 10 hours, weigh the tubes again. Due to diffusion, the tubes should experience weight loss as water exits them when immersed in the solutions.
