5. Predict the vapor pressure of a solution prepared by mixing 35.0 g solid sodium sulfate (molar mass = 142 g/mol) with 175 g water at 25°C. The vapor pressure of pure water at 25°C is 23.76 torr. 6. A solution is prepared by mixing 5.81 g acetone (molar mass = 58.1 g/mol) and 11.9 g chloroform (molar mass = 119.4 g/mol). At 3°5C, this solution has a total vapor pressure of 260. Torr. The vapor pressure of pure acetone is 345 torr and that of chloroform is 293 torr. Calculate the vapor pressure of this solution. Is this solution Ideal?
