atomic mass unit, 1/12 of the mass the carbon 12, the most common carbon isotope. Try a periodic table.

An atomic mass unit (amu) is defined as 1/12 of the mass of one atom of the Carbon 12 isotope. It may also be called a dalton (da). It is the number given below the elements letter symbol on the periodic table.

amu means Atomic Mass Unit and it is found by counting up the number of neutrons and protons because each weighs 1 amu (note: electrons are not counted in this process becaus electrons weigh nearly 0-0.001)

atomic mass unit, it's one-twelfth the mass of a carbon-12 atom

automic mass units. Use periodic table. Its just how much the atom weighs.
