## What are fractional abundances?

Abundance shown as a fraction is called fractional abundance. Natural abundance is shown as percentage, but fractional abundance is shown as fraction, a number from 0 to 1. Also, fractional abundance is a single value , and not a range , but natural abundance is usually a range of values.

## What is fractional abundance?

Fractional Abundance or % Natural Abundance means the same. It refers to the abundance of isotopes of a chemical element as naturally found on a planet. The fractional abundance normally represented as a percentage, of each isotope of a given element in nature.

## What is the formula for abundance?

How do you calculate the percentage of abundance based on mass? Calculate the average atomic mass using the atomic masses of each isotope and their percent abundances. Divide each percent abundance by 100 to convert it to decimal form. Multiply this value by the isotope’s atomic mass.
