The atomic mass number is the total number of nucleons (protons and neutrons) in the nucleus.
If the unknown nucleus has twice the volume of a nucleus with 67 nucleons, it means that it has twice the number of nucleons.
Therefore, the atomic mass number of the unknown nucleus would be 2 times 67, which equals 134.
Problem 08 An unknown nucleus has twice the volume nucleus with 67 nucleons What the atomic mass number of the atom?
