The result you obtained during measurement is in mg element per
liter of the solution examined. If you've measured original sample,
without any previous preparation and/or dilution, the result
obtained is the final one (mg/L = ppm). If you've prepared your
sample prior to analysis, some additional calculation is
needed.
Assume, that you digested 500 mg of the soil in acid, and the
final volume of your sample is 25 ml. The solution was measured on
ICP-AES and 0.5 mg/L Cu was found. How much Cu the soil
contains?
25000 microliter / 500 mg (or 25 ml / 0.5 g) = 50. This is your
dilution factor. Multiply your measured result by this factor
0.5 mg/L Cu * 50 = 25 mg Cu per 1 kg of the soil.
Of course, if you diluted your digested sample during the
measurement, this dilution factor also must be taken into
account.

Definition1/16
If you add the exact mass of the protons, neutrons, and
electrons in an atom you do not get the exact atomic mass of the
isotope. The diference is called the mass defect. The difference
between the mass of the atomic nucleus and the sum of the masses of
the particles within the nucleus is known as the mass defect.
