Understanding N2 (Dinitrogen)
N2, or dinitrogen, is the most abundant gas in Earth’s atmosphere, making up approximately 78% of the air we breathe. It consists of two nitrogen atoms (N) bonded together by a strong covalent bond. To determine the mole mass of N2, we need to consider the atomic masses of nitrogen atoms.
The atomic mass of nitrogen (N) is approximately 14.00674 amu. Since N2 contains two nitrogen atoms, we can calculate its mole mass as follows:
Molecular Mass of N2 = 2 × Atomic Mass of Nitrogen (N)
The Molecular Mass of N2 = 2 × 14.00674 amu
Molecular Mass of N2 ≈ 28.01348 amu
So, the mole mass of dinitrogen (N2) is approximately 28.01348 amu.
