Expected mass formula

WebThe exact massof an isotopic species (more appropriately, the calculated exact mass[9]) is obtained by summing the masses of the individual isotopes of the molecule. For example, the exact mass of water containing two hydrogen-1 (1H) and one oxygen-16 (16O) is 1.0078 + 1.0078 + 15.9949 = 18.0105 Da. WebSep 20, 2024 · Clearly the actual average atomic mass from the last column of the table is significantly lower. Why?
