The average atomic mass of boron has to be calculated. Concept Introduction: Average atomic mass: Each isotope contributes to the average atomic mass based on its relative abundance. Multiplying the mass of an isotope by its fractional abundance (not percent) will give the contribution to the average atomic mass of that particular isotope. The average atomic mass can be calculated by using following formula, A v e r a g e a t o m i c m a s s = ∑ i = 1 n ( m a s s ) ( a b u n d a n c e )
