Interpretation: The window representing the solute particles in the same volume of solution needs to be determined when the amount of solvent is doubled.
Concept Introduction: When in a solution, number of solvent particles increases, solution becomes dilute or its concentration decreases. In this case, same volume of solute contains less number of solute particles.
Explanation of Solution
According to question, window A represents solute particles in given volume of solution. Here, number of solute particles A is 10. Now, if amount of solvent is doubled but volume remains the same, the concentration of solution decrease. As concentration of solution decreases, number of solute particles in given volume of the solution decreases or becomes half.
Therefore, now, number of solute particles in given volume will he half of the initial value that is 5.
The correct window representing it is (C).
