The formula to calculate the Natural Abundance (NA) is:
\[ NA = IM \cdot \left( \frac{IA}{100} \right) \]
Where:
Natural abundance refers to the relative proportion of isotopes of a chemical element as naturally found on Earth. It is usually expressed as a percentage and represents the average mass of those isotopes in a given sample. This value is important in various scientific fields, including chemistry, physics, and geology, as it affects the atomic weight of elements and can influence the outcome of chemical reactions and physical processes.
Let's assume the following values:
Using the formula to calculate the Natural Abundance:
\[ NA = 12.01 \cdot \left( \frac{98.89}{100} \right) = 11.88 \, \text{u} \]
The Natural Abundance is 11.88 u.
