The increase in the temperature of the aqueous solution will result in decrease of its________________?
Correct answer: D. Molarity
- A. Weight % of the solute
- B. Mole fraction of the solute
- C. Molality
- D. Molarity
Explanation
On heating, the solution volume generally expands while the amount of solute remains constant, so molarity decreases. Molality, mole fraction, and weight percent remain unchanged if no material is lost.
