Calculating Average Atomic Mass of an element with isotopes

Calculating Average Atomic Mass of an element with isotopes
In this video I show you how to use isotopes and their percent abundance and be able to calculate the average atomic mass of an element.

You need both the isotope mass and percent abundance of each to do this.

Example formula:
(Mass 1 * Abundance 1) + (Mass 2 * Abundance 2) + (Mass 3 * Abundance 3)

NOTE: be sure to convert your percent to a decimal for each calculation in the process.
