Explanation / Answer

Supposing that Atomic Mass = Atomic Number + #NumberOfElectrons
An element having an Atomic Mass of 9.01 and an Atomic Number of 4
The number of atoms in the element = 5.01, which indicates that
Most atoms of this element contain 5 neutrons.
This is because some isotopes might have one more neutron.
And also because the weight of electrons is considered negligible.
