i want to know how to conversion volume fraction to mole fraction with this gas
i can use pro/ii and dwsim. how can i do this by these programs??
 
You can consider these close to ideal gasses, so vol% = mole%.
 
You should be able to see stream composition presented in a variety of units in a window or a report that those simulation programs generate once a simulation successfully runs. You should be able to find instructions on how to see these results from the software's Help menu or searching online. At that temperature and pressure combination, you should expect the volume and mole fractions to be very close for the reason that Compositepro has given.
