Average Atomic Mass: Average Atomic Mass Worksheet Pdf
Average atomic mass is a weighted average of the masses of all the naturally occurring isotopes of an element. It is calculated by multiplying the mass of each isotope by its relative abundance and then summing the products.
For example, chlorine has two naturally occurring isotopes, 35Cl and 37Cl. The mass of 35Cl is 34.96885 amu, and its relative abundance is 75.77%. The mass of 37Cl is 36.96590 amu, and its relative abundance is 24.23%. The average atomic mass of chlorine is calculated as follows:
“`(34.96885 amu x 0.7577) + (36.96590 amu x 0.2423) = 35.453 amu“`
