Question

define atomic mass unit and determine its value in si​

Answer 1

Answer:

In chemistry, an atomic mass unit or AMU is a physical constant equal to one-twelfth of the mass of an unbound atom of carbon-12. It is a unit of mass used to express atomic masses and molecular masses. ... The "unified atomic mass unit" is a physical constant that is accepted for use in the SI measurement system
