# Ammonium Bromide [NH4Br] Molecular Weight Calculation

The molecular weight of Ammonium bromide [NH4Br] is 97.94274.

Ammonium bromide [NH4Br] is an inorganic compound of three elements: Nitrogen, Hydrogen, and Bromine. The molecular weight of Ammonium bromide is 97.94274 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Nitrogen, Hydrogen, and Bromine.

# CALCULATION PROCEDURE: Ammonium bromide [NH4Br] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Ammonium bromide molecule.
You will know different atoms and their number in an Ammonium bromide molecule from the chemical formula. The chemical formula of Ammonium bromide is NH4Br. From the chemical formula of Ammonium bromide, you can find that one molecule of Ammonium bromide has one Nitrogen (N) atom, four Hydrogen (H) atoms, and one Bromine (Br) 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 Bromine (Br): 79.904 (Ref: Jlab-ele035)

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

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

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

Number of Bromine atoms in Ammonium bromide: 1
Atomic weight of Bromine (Br): 79.904
Total weight of Bromine atoms in Ammonium bromide: 79.904 x 1 = 79.904

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

Molecular weight of Ammonium bromide: 14.00674 (Nitrogen) + 4.032 (Hydrogen) + 79.904 (Bromine) = 97.94274

So the molecular weight of Ammonium bromide is 97.94274.
