Raoult's Law
1) Find the vapor pressure of a solution made by dissolving 35.0 g of sodium sulfate dissolved in 175 mL of water at 25 C.
2) A solution is prepared by mixing 11.62 g acetone and 11.9 g chloroform. At 35C, this solution has a total vapor pressure of 260 torr. Is this solution an ideal solution? The vapor pressure of pure acetone and pure chloroform at 35C are 345torr and 293 torr, respectively.
