Homework Statement
"Suppose you were to collect 1.0 L air by passing it slowly thorugh water at 20C and into a container. estimate the mass of water vapor in the collect air, assuming that the air is saturated."
I don't know where to even begin. at first i thought it had something to do with henry's law, but that didn't lead me anywhere
Homework Equations
Henrys Law
S=kH X P
The Attempt at a Solution
I have no idea, I read the chapter on physical equilibria throughly, but I can't answer this question. All I need is the conceptual understanding as to how I would solve this problem. The only way I thought of doing this is
1. find the solubility of air in water (henry's constant given)
2. plug in the vapor pressure of water at 20C for P
3. Obtain solubility
4. then I have the solubility of air in water
5. that didn't get me anywhere
I couldn't think of anything else, conceptual guidance would be appreciated
the answer is I don't know where to even begin. at first i thought it had something to do with henry's law, but that didn't lead me anywhere
the answer is 0.017g
thanks !
