4) A solution is prepared by mixing 5.81 g acetone (MM C3H60 = 58.1 g/mol) and 11.9 g chloroform (MM HC?C13 119.4 g/mol). At 35°C, this solution has a total vapor pressure of 260 torr. Is this an ideal solution? The vapor pressure of pure acetone and pure chloroform at 35°C are 345 and 293 torr, respectively.
