ntroduction:
Oopes are atoms of the same atomic number (same element) having different masses due to different num
neutrons. The average atomic mass of an elemert is the weighted average of the masses of the isatape
lement The weighted average takes inte acceunt beth the mass and rektve abundance of each sateg
Ccurs in nature.
Purpose:
n this experimer, you will perfarm the necenary cakulatioms to determine the average atomic mass of th
ictitious elemert Penguinm The three different hatopes of Penguinium are colared red, white and
bur job will be to abtain a sample of Penguinm and determine the mam of each isotope and the relative
bundogeance of each isotope. Fram this data, you will cakulate the weighed average mas, or ama
Penguinium ***Unlike real sotopes, each isotope of Penguinum differs slightly in mas. For
he red bears weigh exactly the same (f these were real natopes they would So you will determine the
mass of each type of isotope (Table 1), and well pretend that all of each satope weighs exactly shat thea
s. Then you can cakulate the weighad average mas(a ka average atomk mas) of Penginkm 1
