Question

What is mean by unified atomic mass unit?

Answer 1

☆ ANSWER..

▪︎In 20 century various instruments for accurate determination of atomic masses were developed.

▪︎Therefore, instead of relative atomic mass, it is not possible to determine the atomic masses in KG.

▪︎By unified atomic mass unit, call the daltons has been accepted as the unit for expressing atomic mass unit 1 u = 1.66053904 x 10-²⁷ kg

QUESTION -

What is mean by unified atomic mass unit?

ANSWER -

The atomic mass unit (abbreviated as amu or simply u) is a unit that is used to express the atomic masses of atoms and molecular masses of compounds. One atomic mass unit is a mass unit equal to exactly one twelfth (1/12th) the mass of one atom of carbon-12.

✔️The atomic masses of all elements have been found relative to an atom of carbon-12.

One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.
