Connecting two vessels
« on: August 24, 2012, 11:06:25 AM »
Two vessels of the same volume (in one is water, in the other is a gas whose 2ml are dissolved in 1ml of water under standard conditions) were connected. What will be the pressure when equilibrium is established, if the starting pressure and temperature are 120kPa and 273K?

I know the Henry's law and the gas laws, but I don't know what to do here. I don't know the volume of water and the amount of the gas.

If you assume volume of V for both tanks - will it be easier? Or 1L if you prefer to work on numbers and not symbols?

Okay, I have 1dm3 of water and 1dm3 of gas, when they connect, all of the gas will be absorbed, right, nut then there is no pressure, only of water vapors.
