A 20 liter stainless steel container was charged with 2 atm of hydrogen gas and 3 atm of oxygen gas. A spark ignited the mixture, producing water. What is the pressere in the tank at 25 degrees C? If the reaction in the above problem occurred at 125 degrees C, what would the pressure in the tank be? I know that this problem has to do with Dalton's Law of Partial Pressures and since water is involved, the pressure of water vapor will have to be factored in. But other than that, this problem is much more complex than what we have been doing and I would appreciate some help with it. Thanks.
