Today in class we did the Beanium lab, where we calculated the average atomic mass of the beans. Each bean represented a different atom and the different colors represent different isotopes.
When calculating the total mass of all of the atoms of the isotopes, all we had to do was measure each bean color on a scale. Then, the average mass of each isotope was measured by dividing the total mass, by the total number of atoms in each group. Next, we calculated the percent abundance of the isotope by dividing the number of atoms of the isotope by the TOTAL number of atoms in the sample. Using this information you can then calculate the average atomic mass of the beanium atom using the formula ((mass * %))+((mass*%))...= average atomic mass
