You place 25 mL of 10% NaCl in a dialysis bag and place the bag in a beaker containing 100 mL of distilled water. After 24 hours, what is the concentration of NaCl in the beaker? Show your calculations.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
