A sealed flask contains 0.60 g of water at 28 degrees celcius. The vapor pressure of water at this temperature is 28.36 mmHg.
What is the minimum volume of the flask in order that no liquid water be present in the flask?

I tried to solve this problem earlier using PV = nRT, but I kept getting the wrong answer.

bobpursley,
I don't know what you did.
you have the vapor pressure, you have the moles of water (convert mass), you have the temp, solve for V
I can check your work.
