An unknown element has two naturally occurring isotopes. Isotope 1 has a mass of 121.0 amu and an abundance of 55.10%. Isotope 2 has a mass of 123.0 amu. What is the atomic mass of the element?

the atomic weight of an atom containg 9 protons 9 electrons and 10 neutrons?

NucleonsThe term nucleon refers to the particles found in the nucleus of an atom, namely protons and neutrons. A single hydrogen atom (one proton plus one electron) has a mass of 1.007825 amu. A single neutron has a mass of 1.008665 amu. Note that amu stands for "atomic mass unit" and is sometimes abbreviated with the symbol uu. 1 uu is equivalent to 1.665387×10-27 kgPart A Calculate the mass defect of the fluorine nucleus 19-9F. The mass of neutral  19-9F is equal to 18.998403 atomic mass units.   Part B Calculate the binding energy E of the fluorine nucleus 19 9F  (1eV=1.602×10-19J)   Part C Calculate the binding energy per nucleon of the fluorine nucleus 19-9F
