The mass number of an atom is defined as the sum of the number of protons and the number of neutrons in that atom.

So, if m is the mass number, p is the number of protons and n is the number of neutrons, we have:

[tex]m=p+n[/tex]

We have that:

[tex]\begin{gathered} p=30 \\ n=34 \\ m=30+34=64 \end{gathered}[/tex]

So, the mass number is 64.
