Heart pumps blood to your body and it has four chambers. Two Atriums and Two Ventricles.
You can confidently conclude that the concentration of the unknown solution is less than 100ppm. Because the concentration of the liquid in the beaker is higher than that of the unknown solution that is why water move out of the dialysis bag into the beaker of water. Thus, the solution inside the beaker is an hypertonic solution, that is why it deflated the dialysis bag.
