HEY MATE HERE IS YOUR ANSWER.....
Atomic mass is the total number of nucleons (protons and neutrons) in the nucleus. Carbon-12 has 6 of each.
Because some of the mass of those nucleons “disappears down the potential energy well” of the strong interaction, there is a significant variation of the mass per nucleon; also neutrons are a bit heavier than protons. So the actual mass of a given nucleus will be slightly less than the sum of the masses of its protons and neutrons; this difference varies from nucleus to nucleus, but it is never enough to throw off the interpretation of “atomic weight” as the number of nucleons.
Carbon-12 is a logical candidate for calibration of the “mean mass of a nucleon” because it has an equal number of both types, it has a fairly “average” binding energy, it is readily available, and natural carbon (on Earth) inabout 99% carbon-12.

Hello friend!!
Here's the answer....
Carbon with isotope 12 has a whole number ( without any decimals) whereas the other elements are expressed in approximate atomic mass... thus carbon 12 has been chosen as the standard element for measuring the atomic mass of other elements.
I hope it helps you....
