WebThe issue with using an arithmetic mean for calculating something like average atomic mass is that it assumes that all the masses of the isotopes are present in nature in equally abundant amounts. And of course they are not, some isotopes are more stable than others leading to wildly different abundances often. ctm tectrolWebJun 2, 2024 · One mole of carbon is 6.022 x 10 23 atoms of carbon ( Avogadro's number ). This relation is then used to 'convert' a carbon atom to grams by the ratio: mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10 23 atoms. Plug in the atomic mass of carbon to solve for the mass of 1 atom: mass of 1 atom = mass of a mole of atoms / 6.022 x 10 23. ctm templateWebThe mass of an atom can be calculated by adding up the masses of its protons, neutrons, and electrons.
