Mass number is equal to the sum of number of neutrons (neutral subatomic particle) and number of protons (positively charge particle).

Mass number  =[tex]number of protons + number of neutrons[/tex]

Now, atomic number is same as the number of protons i.e. atomic of nitrogen is 7 . Thus, number of protons is also equal to 7.

Therefore,

Mass number  =[tex]7 + 6[/tex]

= [tex]13[/tex]

Hence, mass number of nitrogen is equal to [tex]13[/tex].
