What I'm trying to do is estimate the chemical abundances at different ages of the universe. If I have the metallicity of a star at a given redshift, then I know both its age and its metallicity (and a rough estimate of the proportion of non-H/He elements). Then, if I have this data for varying "weighted metallicities" (metallicity by percentage * mass) for many different redshifts/ages, I can estimate the proportion of elements at varying ages.

Thanks.
