Hi Guys,

I have a bit of a problem with some course work please help:

The question is: Determine the atomic fractions Xc and Xo (carbon and oxygen) for the following gas composition at room temperature:
50% H2, 30% H2O, 20% CO2

I am sure you need to work out the partial pressures for each of the substances at room temp and then determine how much carbon/oxygen will be present, however i have no idea how to do this

Please help

Much appreciated.

If those are number percentages (rather than mass percentages) then a particular sample of the mixture might have:

50 H2 molecules
30 H2O molecules
20 CO2 molecules

If this sample were to be dissociated into its component atoms and they were binned and counted, how would that look?
 
Hi Gneill,

That is the answer than i am going with H:O:C = 16:7:2 so O = 28% and C is 8%

Thanks for your help
