Increasing the temperature of an aqueous solution will cause decrease in its________________?
Correct answer: C. Molarity
- A. Molality
- B. Mole fraction
- C. Molarity
- D. Weight percent
Explanation
Molarity is moles of solute per unit volume of solution, and heating usually expands the solution, reducing this ratio. Molality, mole fraction, and weight percent remain unchanged when no material is added or removed.
