Question

Why are atomic masses called as relative atomic masses??

Answer 1

Explanation:

Atomic mass is also called Relative Atomic Mass as it is calculated as the no. of times an atom of an element is heavier than 1/12 th the mass of an Carbon atom ( C-12 isotope ) .

Answer 2

Answer:

Atomic masses are called relative atomic masses because atomic mass determines the number of times an atom of an element is heavier than 1/12 of a C-12 atom.

explanation :

Basically, there is a comparison happening here. We are finding the atomic mass of an atom relative to 1/12th of the mass of carbon-12 atom.
