Ammonium Hydroxide [NH4OH] Molecular Weight Calculation

The molecular weight of Ammonium hydroxide [NH4OH] is 35.04614.

Ammonium hydroxide [NH4OH] is an inorganic compound of three elements: Nitrogen, Hydrogen, and Oxygen. The molecular weight of Ammonium hydroxide is 35.04614 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Nitrogen, Hydrogen, and Oxygen.

CALCULATION PROCEDURE: Ammonium Hydroxide [NH4OH] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Ammonium hydroxide molecule.
You will know different atoms and their number in an Ammonium hydroxide molecule from the chemical formula. The chemical formula of Ammonium hydroxide is NH5O. From the chemical formula of Ammonium hydroxide, you can find that one molecule of Ammonium hydroxide has one Nitrogen (N) atom, five Hydrogen (H) atoms, and one Oxygen (O) 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 Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

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

Number of Hydrogen atoms in Ammonium hydroxide: 5
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ammonium hydroxide: 1.008 x 5 = 5.04

Number of Oxygen atoms in Ammonium hydroxide: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Ammonium hydroxide: 15.9994 x 1 = 15.9994

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

Molecular weight of Ammonium hydroxide: 14.00674 (Nitrogen) + 5.04 (Hydrogen) + 15.9994 (Oxygen) = 35.04614

So the molecular weight of Ammonium hydroxide is 35.04614.
