1. Molecular Formula: Nitrogen exists as a diatomic molecule, meaning it has two nitrogen atoms bonded together (N₂).
2. Atomic Mass: The atomic mass of nitrogen is approximately 14.007 atomic mass units (amu).
3. Molecular Mass: To find the mass of a nitrogen molecule, we multiply the atomic mass by the number of atoms in the molecule:
Molecular mass of N₂ = 2 * 14.007 amu = 28.014 amu
4. Conversion to Grams: 1 amu is equal to 1.66054 × 10⁻²⁴ grams.
Mass of one nitrogen molecule = 28.014 amu * (1.66054 × 10⁻²⁴ g/amu)
= 4.6566 × 10⁻²³ grams
Therefore, the mass of one nitrogen molecule (N₂) is approximately 4.6566 × 10⁻²³ grams.
