Question

The atomic mass of the carbon is:

Answer 1

A single atom’s atomic mass is simply its total mass and is usually expressed in units of the atomic mass unit or amu. An atom of the carbon with six neutrons, carbon – 12 has an atomic mass of 12 amu by the definition.

Complete answer:
A complete element's atomic mass is the mass of one atom of that element.
With the assistance of the mass spectrometry they can be analyzed in a reasonably precise way.
The mass of one atom can be determined compared to the mass of another by the experimental means.
As the first element with atomic number 1 is hydrogen and the relative atomic mass of hydrogen is 1.
The unit of the atomic mass is the atomic mass unit.
It is defined as a mass equal to 1/12 of the mass of a single atom of the carbon-12.
It is equivalent to grams.
Mean atomic mass takes into consideration the distribution of the isotopes (relative to each other found in the earth)
The most common carbon isotope for instance, is carbon – 12 which has a relative abundance of 98.89%.
The carbon – 13 amu and carbon 14 atomic masses are 13.003 amu and 14.003 amu, respectively.
The average atomic mass of carbon is 12.011 amu.

Additional information:
Definition of the atom: Atom is a smallest part or unit into which the matter can be divided without the release of electricity charged particles.

Note:
As an approach to understand atomic mass we saw the basics of atomic mass and the definition of the atomic mass and then understood how do we measure atomic mass of any substance and then we discovered the atomic mass of the carbon which is 12.011 amu.
