The sugar solution that is the most concentrated is 15 g of sugar in 25 mL of water.

CONCENTRATION:

  • The concentration of a solution is related to the amount of a substance and its volume.

  • The concentration of a solution is directly proportional to the amount of a substance but inversely proportional to the volume.

  • This means that the concentration increases with an increasing amount of substance but decreases with an increasing volume.

  • According to this question, 15g of sugar is the highest amount and it dissolves in 25mL of water, which is the lowest volume. Therefore, it is the most concentrated sugar solution.
