Dear all,
I know the atomic weight to weight percentage conversion of individual elements.
As graphite is composed of carbon and oxygen.
How do we convert 40 atomic % of graphite in to weight %?
40 atomic% of what? Oxygen load? That would mean your stoichiometry is C1.5O, that sounds like quite a lot for still calling it "graphite".
Anyway, in that case you need to multiply by the atomic masses, so the mass ratio is C:O=12*1.5:16*1=9:8. So it would be 53 mass% carbon and 47 mass% oxygen.
Thanks for the early response.
Its not clearly mentioned in the literature whether it is % Carbon or % oxygen.
Although I have given the link of paper for your reference.
Do check the page number 64, first line in the experimental procedure.

This looks more like a composite of Graphite and Aluminium, so it's 40% C and 60% Al, there is no oxygen specified.
In that case it's CAl1.5, so C:Al=1*12:1.5*27=12:40.5, so it's 23 mass% C and 77 mass% Al.
