Misconception: Atomic mass is a fixed value
Misconception: Atomic mass is the same as atomic number
At its core, finding the average atomic mass involves calculating the weighted average of the masses of an element's naturally occurring isotopes. This is achieved by multiplying the mass of each isotope by its relative abundance and summing the results. For example, the average atomic mass of carbon is calculated as follows:
