A solution of sodium chloride in water has a vapor pressure of 18.5 torr at 25C.
What is the mole fraction of NaCl in this solution? What would be the vapor pressure of this solution at 48C? The vapor pressure of pure water is 23.8 torr at 25C and 83.7 torr at 48C.

I've tried this as well as went to my tutor, but we couldn't get it. Can someon ehelp me? I need it by tonight
