Relative isotopic mass formula

WebAug 8, 2024 · Boron has two isotopes so we will use the Equation 2.3.1 and substitute the relative abundances and atomic masses of Boron into Equation 2.3.1: Atomic mass = ( 0.20) ( 10) + ( 0.80) ( 11) = 10.8 amu. The mass of an average boron atom, and thus boron's atomic mass, is 10.8 amu. Example 2.3. 1: Atomic Weight of Neon.
