Question

Define the atomic mass unit.​

Answer 1

$\huge\boxed{\fcolorbox{red}{ink}{Verified Answer}}$

The dalton or unified atomic mass unit 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. The atomic mass constant, denoted mᵤ is defined identically, giving mᵤ = m/12 = 1 Da.

Explanation:

• An atomic unit of mass is defined as accurately 1/12 the mass of a carbon-12 atom. The carbon-12 atom has six neutrons and six protons in its nucleus. 1 AMU = Average of the proton rest mass and the neutron rest mass. 1 AMU = 1.67377 x 10 -27 kilogram or 1.67377 x 10 -24 gram.
