Which of the following is the most likely mass for an atom of silver-109?

Question

Quizplus · Accepted Answer

The mass of an atom in atomic mass units (amu) is very close to its mass number, but due to the binding energy and the mass defect, it's not exactly the mass number. Silver-109 has a mass close to 109 amu, but with slight deviations. The option D, 108.905 amu, is the most accurate representation of this, reflecting the actual measured atomic mass of silver-109, which accounts for these factors.
