How many moles of water per breath?
P=vaporpressure V is volume of breath
T is temp.
Now, knowing moles per breath, convert that to one hour. Finally convert moles water to grams water.
thanks so much!! i thought it had something to do with partial pressures.
actually, it does. You have to use the partial pressure of water in the equation, just as I said, and as GK said.
I am irked. GK gave you a correct answer 20 min ago, and you posted again. Besides being rude, it wastes volunteers time. Please don't do that again.
sorry about that,i am just so busy.i am a really good student at chem,just had a really big doubt.the question was confusing and i thought mayb GK mistook it as well. but it wont happen again
Your question has already been answered here:
The moles of a gas in a mixture, in this case water vapor,depends on the partial pressure of that gas independently of any other gases present. That comes out of Dalton's Law of Partial Pressures. I gave you a complete procedure on how to calculate the moles of H2O vapor. The moles can be easily converted to grams. Do multiple postings of the same question will not get you a more detailed answer.
