Final answer:

The aqueous solution with the highest boiling point is 0.10M Na2SO4 because it produces the most solute particles when dissociated, leading to a more significant boiling point elevation.

Step-by-step explanation:

The boiling point of a solution increases with the number of solute particles present. This concept is known as boiling point elevation. The more solute particles in a solution, the higher the boiling point. This is due to the disruption of intermolecular forces caused by the added particles.

The answer is C 0.10M Na2SO4, because it produces the most particles when it dissociates in water. Sodium sulfate (Na2SO4) dissociates into three particles: 2 sodium ions and 1 sulfate ion.
