I am not certain if I understand the question. vapor pressure indicates the tendency for molecules to move to the vapor state. If forces bind the molecules together, bp will be highter, and for a given temperature, vapor pressure is lower. If forces disperse molecules, bp is l...

2H2+O2>>2H2O They should have gotten 1.01liters of water vapor, or 1/22.4 * 18 grams. as the vapor condenses, and cools to 25C, the H+ concen will be 1*10^-7 moles/liter Milliliters of product? One has to have the temp and pressure.

How can I tell you the final volume without knowing the initial volume? You dilute it 60, meaning one part original,59parts solvent. so the final volume is sixty times the original. The final concentration is .2percentmilliosmoles
