You set up an experiment where you place a sealed (clamped) dialysis tube cell in a beaker of water. The solution in the dialysis tube cell is 25%NaCl solution and the solution in the beaker is 1%NaCl solution. The solvent for both is water. Before you place the tube in the cell, after it has been filled and clamped, you find the mass of the ‘cell’ after carefully drying off any water on the outside or on the clamps. You also find the mass of the cell after it has been placed in the beaker solution for 30 minutes after carefully drying off the outside of the ‘cell’ and clamps. The masses are in the table below. Mass in grams of dialysis tube cell Initial Mass 25.0g Final Mass after 30 minutes 28.7g Using this information, explain the difference in mass before and after submerging the cell in the beaker solution for 30 minutes.

Question
You set up an experiment where you place a sealed (clamped) dialysis tube cell in a beaker of water. The solution in the dialysis tube cell is 25%NaCl solution and the solution in the beaker is 1%NaCl solution. The solvent for both is water.
Before you place the tube in the cell, after it has been filled and clamped, you find the mass of the ‘cell’ after carefully drying off any water on the outside or on the clamps. You also find the mass of the cell after it has been placed in the beaker solution for 30 minutes after carefully drying off the outside of the ‘cell’ and clamps. The masses are in the table below.
