...................... is the atomic mass of Nitrogen.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 14.
The atomic mass of Nitrogen is approximately 14 atomic mass units (amu). This value represents the average mass of nitrogen atoms, taking into account the relative abundances of its isotopes. Nitrogen has two stable isotopes, nitrogen-14 and nitrogen-15, with nitrogen-14 being the most abundant. The atomic mass is a critical property used in various scientific calculations, including stoichiometry in chemical reactions, molecular weight determination, and in understanding the behavior of nitrogen in different chemical and physical processes.
