What is Atomic Mass in Chemistry?
Explanation:
Atomic mass is the weighted average of the masses of the isotopes present in a natural sample of an element and is expressed in atomic mass units (amu).
Final Answer:
Atomic mass is the weighted average of the masses of the isotopes present in a natural sample of an element. It is expressed in atomic mass units (amu), which is equal to one-twelfth the mass of a carbon-12 isotope. The atomic mass listed in the periodic table is the weighted average of the masses of the isotopes present in a natural sample of the element. For example, the atomic mass of helium is 4.0026 amu, while the atomic mass of sulfur is 32.06 amu.
