That's a renormalization on a volatile-free basis of estimates of the Solar photosphere composition ("Sol" for short"); I believe that particular composition is the "recommended" value from Lodders et al. (2009).
In the conversion table that appears in in columns P to AA, you would use row 6 instead of row 5, so you would take oxides (which could be entered in columns B-L instead of elements) and multiply those oxides by the correction factors in row 6. Then be sure to edit the headers, so if you are performing the multiplication in columns Q to AA, then the header in cell Q9 becomes "Element, weight proportion" (instead of "Oxide, weight proportion"), and cell A9 wold be changed to "Oxide %".
Hi Amina - I later realized that this video says nothing about how to deal with Oxygen. I've recorded (and will soon post) a new video to illustrate the conversion of oxides to elements, and also how to deal with O, including some caveats for systems that are possibly very O-rich. Thank your for your question. And my apologies for not thinking it through earlier.
Perfect,need this for thesis
Thanks so much Keith, your video is really useful!
Hal, Nice explanation, i dont understand , where u got the first row value like sol , could expalin that row.

Thank you so much for sharing Dr. Putirka. By the way, I guess the conversion factor of K seems to be a little bit problematic in the video.
Thank you for that correction. I'll add a note to the description
Thank you, so useful ...
But, how to convert oxides to atoms percentage?

Appreciate it!
