Molecular Weight Of Ammonia: Ammonia, with the chemical formula NH3, is a compound that holds immense significance in various fields, from agriculture to industrial chemistry.
Understanding its molecular weight is essential for grasping its properties, applications, and how it behaves in chemical reactions. In this article, we will explore the molecular weight of ammonia, its calculation, and its relevance in different scientific and industrial contexts.
Molecular Weight Of Ammonia
What is Molecular Weight?
Molecular weight, also known as molecular mass or molar mass, is the sum of the atomic masses of all the atoms present in a molecule. It can be denoted in atomic mass units (amu) or grams per mole (g/mol). Molecular weight serves as a bridge between the microscopic world of atoms and molecules and the macroscopic world we can observe and measure.
Molecular Weight of Ammonia (NH3)
To determine the molecular weight of ammonia (NH3), we need to consider the atomic masses of its constituent elements:
- Nitrogen (N) has an atomic mass of approximately 14.01 amu.
- Hydrogen (H) has an atomic mass of approximately 1.008 amu.
Now, let’s calculate the mole weight of ammonia (NH3):
mole weight of NH3 = (1 * 14.01 amu for nitrogen) + (3 * 1.008 amu for hydrogen) = 14.01 amu + 3.024 amu ≈ 17.034 amu.
Therefore, the mole weight of ammonia (NH3) is approximately 17.034 amu or 17.034 g/mol.
