oksian1 [2.3K]

Answer:

1 mol per dm3 sodium chloride solution

Explanation:

The liquid that would cause the largest decrease in the mass of the potato stick would be the one with  <u>1 mole per dm3 sodium chloride solution.</u>

<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>

Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.
