Which of the following liquid systems would be expected to have the lowest vapor pressure at room temperature?

Question

Quizplus · Accepted Answer

D) A 1.00 m solution of NaCl in water would have the lowest vapor pressure at room temperature because NaCl dissociates into two ions (Na+ and Cl-), effectively doubling the number of solute particles compared to the non-electrolyte solutions (A, B, C), and thus causing a greater reduction in vapor pressure according to Raoult's law. Pure water (E) would have a higher vapor pressure than any of the solutions because it has no solute particles to lower its vapor pressure.
