Candium average atomic mass

If asked how you find an average, most people respond that you add up the values and divide by how many there were.
The average of 2, 2, 4, and 8 is 16/4 or 4.
But the average can also be found by saying 50% of the values were 2, 25% were 4 and 25% were 8 using the following calculation:
0.50*2 + 0.25*4 + 0.25*8 = 4
The latter method is best used for determining the average mass of an atom of one element. Many elements have a variety of isotopes that occur with frequencies that can easily be measured. Using % to determine the average is far superior to adding up each atom because such a sheer number of atoms exists even within a tiny sample.
