Best Answer

From Wikipedia: "... It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 ..." Thus, to prove that it has a certain mass, you would have to carry out exact measurements of the mass of carbon-12 atoms.

As we know that 1amu not equal to mass of 1 proton then why protium is equal to 1amu?

The atomic mass unit (amu) is defined as 1/12 the mass of a carbon-12 atom. It is a unit of mass that is used to describe the masses of atoms and molecules. The mass of a proton is actually slightly less than the mass of a carbon-12 atom, so it is not equal to 1 amu. However, the mass of a protium atom (which is an atom that consists of a single proton and no neutrons) is very close to 1 amu. This is because the mass of the proton makes up most of the mass of a protium atom. Therefore, protium is often said to be "approximately equal" to 1 amu.
