2. n(H2) / n tot
3. The total mole fraction out of all three is 1.

n(H2) / n tot
what formula is that?

The total mole fraction out of all three is 1.
Oh, Okay!! Thaaank you!
5. total # mol = 0.15 + 0.32 + 0.18 = 0.65 mol

mol fraction of CO = 0.15 / 0.65 = 0.23

mol fraction (wot u asked 4) of H2 = 0.32 / 0.65 = 0.49

blah blah blah.
