What is the Atomic Mass Calculator & How does it work?
Atomic mass is a fundamental concept in chemistry that represents the average mass of an atom of a given element, taking into account all its isotopes. It is typically expressed in atomic mass units (amu) or unified atomic mass units (u). The atomic mass can be calculated using the formula:This formula accounts for the varying masses and abundances of isotopes, providing an accurate representation of the element’s atomic mass.
Atomic Mass = \sum (Isotope Mass × Isotopic Abundance)
Isotope Mass = Mass of a specific isotope
Isotopic Abundance = Fractional abundance of the isotope
Isotopic Abundance = Fractional abundance of the isotope
