Question

Define AMU(atomic mass unit)?​

Answer 1

Answer:

the mass of an atom is called its atomic mass.since an atom is very small it is not possible to measure its mass in grams. therefore mass of a light atom like that of hydrogen or 1/12th of the mass of carbon or 1/16th of the mass of oxygen is taken as a standard unit with which mass of an atom of any other element is compared.carbon is the most suitable and most widely accepted standard unit for the measurement of atomic mass.

this is known as atomic mass unit or amu.
