Chapter 5 Calculating Average Atomic Mass Worksheet Answers Sep 20 2022 0183 32 Were you to simply calculate the arithmetic average of the precise atomic masses you would get 36 frac left 34 969 36 966 right 2 35 968 text amu nonumber Clearly the actual average atomic mass from the last column of the table is significantly lower Why
The term average atomic mass is a average and so is calculated differently from a normal average Explain how this type of average is calculated The element Copper has naturally occurring isotopes with mass numbers of 63 and 65 The relative abundance and atomic masses are 69 for mass of 62 30 for mass of 64 Chapter 5 Worksheet 2 Isotopes and Average Atomic Mass Elements come in a variety of isotopes meaning they are made up of atoms with the sa me atomic number number of protons but different atomic mass numbers These atoms differ i n the number of neutrons The average atomic mass is the weighted average of all the isotopes of an element
