atomic mass unit. A unit of mass equal to 112 the mass of an atom of the most common isotope of carbon (carbon 12), which is assigned a mass of 12 and has a value of 1.660 X 10-24 grams. A hydrogen atom has a mass of 1 atomic mass unit since its mass is 112 the mass of carbon 12.

Answer 2

Answer:

➛Atomic mass:

The atomic mass is defined as the mass of a single atom in atomic mass or (u).

➛Atomic mass unit ("amu" or "u"):

An atomic mass unit is defined as 1/12th of the mass of an atom of carbon-12. It is a unit of mass used to express atomic masses and molecular masses.

➢ The relative atomic masses of all elements have been found with respect to an atom of carbon-12.
