Adding one mole of NaCl to one liter of water will lower the water concentration twice as much as adding one mole of glucose.

Question

Quizplus · Accepted Answer

This is because one mole of NaCl dissociates into two ions (Na+ and Cl-) when dissolved in water, while one mole of glucose does not dissociate into ions. The presence of two particles (ions) in solution will contribute to a greater effect on the concentration of water molecules compared to a single particle (glucose).
