More explanations on the calculation of mean molecular weight.

Although there is an official website TNG Q&A, as a beginner, I still got a little bit confused. After some formulae derivation, I understood why the mean molecular weight is given in the form presented in TNG Q&A.
I would like to post some more detailed explanations on the calculation of mean molecular weight.
It seems that we cannot type math formulae here and I have to paste images here:

fig2.jpg

The relevant websites in these two images are TNG Q&A and The gas temperature.

Hoping that it helps, especially for the beginners like me.
