What is the most common mass number of arsenic?
For elements that have more than one isotope, this number tells you the weighted average of the atomic masses of its stable isotopes. But since arsenic is monoisotopic, that number will tell you directly the atomic mass of its isotope. This means that arsenic’s stable isotope has an atomic mass of 74.992 u .
