Lab 2B: Atomic Mass of Candium

In this lab we used three different isotopes of candium: regular M&M's, peanut M&M's and pretzel M&M's. The purpose of this lab was to practice calculating average atomic mass and to understand isotopes. We also were able to apply our new terms such as atomic number, atomic mass and natural abundance. Our calculated average atomic mass of candium was 1.357g. 

Conclusion:
     1. We compared with another group and found their average atomic mass to be 1.689g. It is possible they have a different answer than us because of human error such as counting incorrectly or not properly weighing the M&M's. It is also possible that each group started with a different amount of each type of M&M, therefore having a differing average atomic mass.

     2. If everyone were given a larger sample of candium, the difference between our average atomic mass and everyone else's atomic mass would become smaller because the larger sample size would create a more similar ratio of each type of M&M's and therefore the result would be more precise.

     3. If we took any piece of candium from the sample and put it on the balance, it wouldn't have the exact same atomic mass that I calculated because each type of M&M has its own distinct weight and none of the M&M's alone could weigh the average mass.
