Hey I was given this problem:(adsbygoogle = window.adsbygoogle || []).push({});

The moles of components of a gas mixture are given. The mole fractions and the apparent molecular weight are to be determined.

The given properties are:

The molar masses of He, O2, N2, and H2O are 4.0, 32.0, 28.0 and 18.0 lbm/lbmol respectively and there are 3 lbmol He, 1.5 lbmol O2, 0.3 lbmol H2O, 2.5 lbmol N2

I am a little bit confused on what a pound mol is I think, in my old chem class it was lb/mol. Anyways the analysis seems simple enough but I can't get the same answer as my instructor.
