The vapor pressure of water is 17.5 mmHg at 20.0°C and 355.1 mmHg at 80.0°C. Calculate the boiling point of water at 720. mmHg.
Added by Jeff B.
Step 1
The equation is: ln(P2/P1) = (ΔHvap/R) * (1/T1 - 1/T2) where P1 and P2 are the vapor pressures at temperatures T1 and T2, respectively, ΔHvap is the enthalpy of vaporization, and R is the gas constant. Show more…

The vapor pressure of pure water at 20.0 degrees Celsius is 17.5 mmHg. What is the vapor pressure of water above a solution of 1.00 M Co(NH2)2 (urea) at 20.0 degrees Celsius?
Water has a vapor pressure of 40.79 kilojoules per mole. When water boils at 100°C, it has a vapor pressure of 760 mmHg. Using this information, calculate the vapor pressure of water at 60°C.
