14.0067 amu
15.999 amu
1.00784 amu
12.011 amu
14
7

Explanation:

The average atomic mass of nitrogen is a known value from the periodic table. Nitrogen has an average atomic mass of approximately 14.0067 AMU. 15.999 AMU is for oxygen, 1.00784 AMU is for hydrogen, 12.011 AMU is for carbon, 14 is the approximate whole - number value (but the more accurate value is 14.0067), and 7 is the atomic number of nitrogen (not the atomic mass).

Answer:

14.0067 AMU
