The mass number of an atom is basically the total number of protons and neutrons.
Answer:8.933572
Explanation:
for an approximate result, multiply the volume value by 3.785
The right answer is 2.
The number of protons contained in a nucleus (called an atomic number) is characteristic of a chemical element. For a given atomic number, the number of neutrons defines different "types" of this element: isotopes. The variation of the number of protons of the nucleus of an atom, during a nuclear reaction for example, causes a change of the element studied.
