# Average Atomic Mass Worksheet Doc

**12) there are 2 isotopes of copper that occur naturally;**

**Average atomic mass worksheet doc**.
The relative abundance and atomic masses are 69.2% and 30.8% respectively.
The natural abundance for boron isotopes is 19.9% 10b (10.013 amu*) and 80.1% 11b (11.009 amu*).
The three potassium isotopes have atomic masses and percent compositions of 39 amu (64.

The term “average atomic mass” is a _____weighted_____average, and so is calculated differently from a “normal” average. To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance (expressed as a decimal). Then, add the results together and round off to an appropriate number of significant figures.

If the abundance of 85rb is 72.2% and the abundance of 87rb is 27.8%, what is the average atomic mass of rubidium? 35.46 amu 6) copper used in electric wires comes in two flavors (isotopes): 69.2% for mass of 62.93u.
