Question

What is the mass of carbon

Answer 1

Atomic mass unit (amu): the mass exactly equal to one-twelfth of the 12 atoms of carbon.

The mass of carbon in the periodic table is calculated as amu 12.01. This is the average atomic mass of carbon. The mass of a carbon atom is not 12.01 amu, but the average mass of a few C atoms is 12.01 amu.
