Choose the aqueous solution with the highest vapour pressure. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. A) 0.50 mol kg^-1 C₃H₈O₃ B) 0.50 mol kg^-1C₂H₆O₂ C) 0.50 mol kg^-1C₆H₁₂O₆ D) 0.50 mol kg^-1C₁₂H₂₂O₁₁ E) They all have about the same vapour pressure.

Question

Quizplus · Accepted Answer

All solutions have the same concentration of nonvolatile solute and are assumed to have ideal van't Hoff factors, so they all lower the vapor pressure of water to the same extent.
