A
3
Q
The relative atomic mass is the average of all of an elements isotopes masses
A
4
Q
Each isotopic mass has a higher abundance/frequency than others. meaning those with a higher abundance will be easier to find
A

Q
Example of calculating RAM:
A
isotopes: Abundances:
Ne-20. 90.48%
Ne-21 9.25%
Ne-22 0.27%
0.9048(20)+0.0925(21)+0.0027(22)
=20.09
=20.10
