    Conversion between mole fractions and volume fractions in gas analysis

    When can you assume that volume percent is the same as mole percent? I've read in another posting that you can assume this at low pressure but I'd like to know why and under what conditions. Note: I have already submitted this thread under a different subject and had various replies...

    Predicting H2S in Liquid and Vapour Phase of Oil

    I've been using a rough 'rule of thumb' to convert the concentration of H2S in oil to the concentration in the vapour phase as being 1ppm w/v ~= 100ppm v/v. Is this a valid estimation? Are there other ways to predict it more accurately? Can anyone describe the reasoning behind it and state any...
