Consider a solution of 15.0 g PF3 in 135 g H2O. The solution has a volume of 145 mL at 298 K, and the vapor pressure of water at this temperature is 23.8 torr. Which of the following are correct regarding this solution? More than one may be correct. The scoring on this question will be corrected after the due date. The solution has a higher boiling point than pure water Hydrogen bonding occurs between PF3 and water PF3 is phosphorus trifluoride PF3 is nonpolar The preferred Lewis structure for PF3 is shown to the right The total pressure is 1292 atm The molality of the solution is 1.14 m The vapor pressure of the solution at 298 K is 23.3 torrExplanation / Answer
the correct statements are
i) hydrogen bonding occurs between H2O and PF3
ii) PF3 is phosphorous trifluoride
iii) the preffered lewis structure for PF3 is shown to be right
