If you collect hydrogen gas over water at a temperature of 45 degrees celcius, what is the volume of jst te hydrogen if the pressure of hydrogen is 1.23 atm and the grams of hydrogen was 2.6? What is the volume of the water?

    You don't make it clear if the pressure of the WET hydrogen is 1.23 atm or the pressure of the DRY hydrogen is 1.23. If it is dry, then use PV = nRT and use 1.23 for pressure. If it is WET, look up vapor pressure H2O @ 45 C, convert to atm, and subtract from the 1.23 and use that in PV = nRT. The volume of water is done use PV = nRT also but use vapor pressure of the water to find volume water.
