Question

Calculate the atomic mass of Nitrogen?​

Answer 1

Answer:

14.0067 u

Explanation:

Nitrogen is element number 7. Using this periodic table, we see the atomic mass of nitrogen is 14.01 amu or 14.01 g/mol.

2. Add up the number of neutrons and protons in a single atom.

Answer 2

First of all what is Atomic Mass?

=> Atomic mass is the sum of number of protons and of neutrons.

Nitrogen contains seven protons and seven neutrons in it.

So, it's atomic mass is 14.

i.e.

Atomic Mass of Nitrogen = Number of protons + Number of neutrons

=> 7 + 7

=> $\textbf{14 u is the atomic mass of Nitrogen}$
