Question

define atomic mass unit . Express it in kg​

Answer 1

Answer:

An atomic mass unit is defined as precisely 1/12 the mass of an atom of carbon-12. ... In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g).
