PRODUCT DESCRIPTION

Most of the atomic masses on the Periodic Table are averages of the stable isotopes. A typical sample of a pure element has a certain percentage of each of the stable isotopes. The average mass is a weighted average based on these percentages. This presentation explains how a weighted average compares to the average computed by most students in the standard way. It also shows how to compute the average atomic mass from mas and percentage data.
