Answer: The mass of a certain element or compound, measured in grams, is divided by the total amount of the material to get its molar mass (mol). It is common practice to determine the molar mass of a compound by summing the quality atomic masses (expressed in g/mol) of the atoms that make up the molecule.
The formula for ammonia, which is also known as the formula for nitrogen trihydride or the formula for azane, is one of the most often used formulae in all of chemistry. Ammonia is a gas that is mostly an inorganic or alkaline substance that is odorless and has a distinctly unpleasant smell. In addition, the element nitrogen is required in significant quantities for a variety of uses in both chemical and industrial processes, and ammonia is an essential supply of nitrogen.
The molecular formula for ammonia is NH3. The formula originates from the chemical structure of ammonia, which includes the following components: The molecule of ammonia has the form of a trigonal pyramid, and the nitrogen atoms are connected to the three hydrogen atoms in the structure. On the other hand, the nitrogen atom only has a single pair of electrons associated with it.
In order to arrive at an accurate estimate of the molar mass of any compound, we need to factor in the molar masses of all of the atoms that make up that molecule. The chemical formula for ammonia is 1 atom of nitrogen and 3 atoms of hydrogen. As a result, the molar mass of ammonia is shown below:
N: 14.0067 g/mol.
H: 1.00794 g/mol.
Therefore, the molar mass of ammonia will be calculated to be 14.0067 g/mol + 3×1.00794 g/mol, which is 17.03052 g/mol.
Hence, The ammonia molecule has a mass of 17.03052 grams per mol.
