The term relative atomic mass is sometimes used as a synonym for average atomic mass. As long as you use atomic mass units in your average mass calculation, however, the two values are numerically identical. Most generally, it is a single number that is used to represent a collection of numbers. The average mass of a molecule is obtained by summing the average atomic masses of the constituent elements. The weighted average (x) is equal to the sum of the product of the weight (w i) times the data number (x i) divided by the sum of the weights:Example.
