What is most likely in Bag G assuming it is sitting in a concentrated sugar solution?

• A

  Distilled water

• B

  concentrated sugar solution

• C

  10% sucrose

• D

  60% sucrose

Answer explanation

The bag G is most likely to contain distilled water. When placed in a concentrated sugar solution, water will move from the bag to the solution to balance the concentration of sugar. This is due to the process of osmosis. Therefore, the bag must have contained a solution with less sugar concentration, which is distilled water in this case.
