• Abundance of the chemical elements - Wikipedia

    en.wikipedia.org/wiki/Abundance_of_the_chemical_elements The abundance of the chemical elements is a measure of the occurrence of the chemical elements relative to all other elements in a given environment. Abundance is measured in one of three ways: by the mass-fraction (the same as weight fraction); by the mole-fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases); or by the volume-fraction.
  • Abundance of the chemical elements

    enacademic.com/dic.nsf/enwiki/223914 The abundance of a chemical element measures how relatively common (or rare) the element is, or how much of the element is present in a given environment by comparison to all other elements. Abundance may be variously measured by the mass-fraction (the same as weight fraction), or mole-fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases), or by volume ...

That table doesn't look correct, if "number of atoms for a thousand carbon atoms" is true. The data may be correct if it is "mass per 1000 mass units of carbon". Icek 15:37, 9 March 2007 (UTC) Icek is right, once I realized he wasn't objecting to the trivially true carbon figure of 1000.
