Determine the mole fraction of water in the air (right at the liquid/vapor interface) above a body of liquid water. The pressure is 1 atm and the temperature room temp or 25o C. We will assume that the mole fraction of water in the liquid phase is xwater=1. However, is xwater=1 really true or are there likely other molecules in tap water? However, is the assumption xwater=1 a good assumption and why? Hint: psat of water is tabulated in the second column of table A.6 in the book and Henrys law constants are tabulated in Table A.9 of the text. Also you may assume the air is an ideal gas. Would Henrys law or Raoults law be better to use in this situation and why?
