The average atomic mass of the element takes the variations of the number of neutrons into account, and tells you the average mass per atom in a typical sample of that element. M(e) = $\sum_{n=1}m(i_{n}) \times p(i_{n})$. The term “average atomic mass” is a _____weighted_____average, and so is calculated differently from a “normal” average.

24 mg is the most common isotope and is thus most heavily weighted in the equation for average atomic mass. Bromine has two isotopes, 79 br and 81 br, whose masses (78.9183 and 80.9163 amu) and abundances (50.69% and 49.31%) were determined in earlier experiments. Explain how this type of average is calculated.
