# Ammonium Chloride [NH4Cl] Molecular Weight Calculation

The molecular weight of Ammonium chloride [NH4Cl] is 53.49144.

Ammonium chloride [NH4Cl] is an inorganic compound of three elements: Nitrogen, Hydrogen, and Chlorine. The molecular weight of Ammonium chloride is 53.49144 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Nitrogen, Hydrogen, and Chlorine.

# CALCULATION PROCEDURE: Ammonium chloride [NH4Cl] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Ammonium chloride molecule.
You will know different atoms and their number in an Ammonium chloride molecule from the chemical formula. The chemical formula of Ammonium chloride is NH4Cl. From the chemical formula of Ammonium chloride, you can find that one molecule of Ammonium chloride has one Nitrogen (N) atom, four Hydrogen (H) atoms, and one Chlorine (Cl) atom.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)
Atomic weight of
Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Chlorine (Cl): 35.4527 (Ref: Pubchem-Chlorine, Jlab-ele003)

Step 3: Calculate the total weight of each atom in an Ammonium chloride molecule by multiplying its atomic weight by its number.

Number of Nitrogen atoms in Ammonium chloride: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Ammonium chloride: 14.00674 x 1 = 14.00674

Number of Hydrogen atoms in Ammonium chloride: 4
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ammonium chloride: 1.008 x 4 = 4.032

Number of Chlorine atoms in Ammonium chloride: 1
Atomic weight of Chlorine (Cl): 35.4527
Total weight of Chlorine atoms in Ammonium chloride: 35.4527 x 1 = 35.4527

Step 4: Calculate the molecular weight of Ammonium chloride by adding up the total weight of all atoms.

Molecular weight of Ammonium chloride: 14.00674 (Nitrogen) + 4.032 (Hydrogen) + 35.4527 (Chlorine) = 53.49144

So the molecular weight of Ammonium chloride is 53.49144.
