Answer:
12.a unit of mass used to express atomic and molecular weights, equal to one twelfth of the mass of an atom of carbon-12.
Carbon-12 is chosen as a reference standard for atomic and molecular masses since the atomic mass of Carbon-12 is exactly 12.000 , which, if you divide by 12, gives you exactly 1.000 Hydrogen, on the other hand, has an atomic mass slightly larger than 1.000.
