Question

What is meant by Unified Atomic
Mass?
​

Answer 1

Answer:

The dalton or unified atomic mass unit is a unit of mass widely used in physics and chemistry.

Explanation:

It is defined as 1/12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. The atomic mass constant, denoted mᵤ, is defined identically, giving mᵤ = m/12 = 1 Da.

Answer 2

Explanation:

The dalton or unified atomic mass unit (symbols: Da or u) is a unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest.
