Calculating Mass Flux and Mass Fractions in CO2 and H2 Injection Experiment

[pyroknife]

I am working on a experiment that injects CO2 and H2 at a specified mass flux. The mass fraction of each is 0.5. Given the total mass flux of the combined species, how would I find the mass flux of each individual specie? I was thinking it would just be a simple halving since the mass fractions are 0.5 each.

And?

And?

Oh I was wondering if that's correct? It seems off intuitively, but I can't explain why.

Seems OK to me.
