A 3.00L sample of gas was collected over water at 45 degrees Celsius. The wet gas exerts pressure of 1.50atm. When dried the sample occupies 1.80L and exerts a pressure of 1.77 atm at 80.0 degrees Celsius. What is the vapor pressure of water at 45 degrees Celsius?
My answer = 0.54atm
I wonder if this is a made up problem. I looked up the vapor pressure of H2O at 45C and found 71.9 mm Hg which is 0.0946 atm.
