What is Average Atomic Mass?
1.
The weighted average of the atmoic masses of the naturally occuring isotopes of an element.
Suppose you had a box of marbles that contain 2 sizes of marbles. If 25% of the marbles have the massses of 2.00g each and 75% have the masses of 3.00g each then the average atomic mass would look like this.
25 marbles x 2.00g = 50g+75 marbles x 3.00g = 225g = 275g / 100 = an average atomic mass of 2.75g.
See
25 marbles x 2.00g = 50g+75 marbles x 3.00g = 225g = 275g / 100 = 2.75g.
See
25 marbles x 2.00g = 50g+ = 275g / 100 = an average atomic mass of 2.75g.
See
25 marbles x 2.00g = 50g+ = 275g / 100 = 2.75g.
See
+75 marbles x 3.00g = 225g = 275g / 100 = an average atomic mass of 2.75g.
See
+75 marbles x 3.00g = 225g = 275g / 100 = 2.75g.

+ = 275g / 100 = an average atomic mass of 2.75g.
See
+ = 275g / 100 = 2.75g.
