Sodium Azide [NaN3] Molecular Weight Calculation

The molecular weight of Sodium azide [NaN3] is 65.00998928.

Sodium Azide [NaN3] Molecular Weight CalculationSodium azide (NaN3) is an inorganic compound of two elements: Sodium and Nitrogen. The molecular weight of Sodium azide is 65.00998928 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Sodium and Nitrogen.

 

CALCULATION PROCEDURE: Sodium azide [NaN3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Sodium azide molecule.
From the chemical formula, you will know different atoms and their number in a Sodium azide molecule. Chemical formula of Sodium azide is NaN3. From the chemical formula of Sodium azide, you can find that one molecule of Sodium azide has one Sodium (Na) atom, and three Nitrogen (N) atoms.

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

Atomic weight of Sodium (Na): 22.98976928 (Ref: Ciaaw-sodium)
Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)

Step 3: Calculate the total weight of each atom present in a Sodium azide molecule by multiplying its atomic weight by its number.

Number of Sodium atoms in Sodium azide: 1
Atomic weight of Sodium (Na): 22.98976928
Total weight of Sodium atoms in Sodium azide: 22.98976928 x 1 = 22.98976928

Number of Nitrogen atoms in Sodium azide: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Sodium azide: 14.00674 x 3 = 42.02022

Step 4: Calculate the molecular weight of Sodium azide by adding up the total weight of all atoms.

Molecular weight of Sodium azide: 22.98976928 (Sodium) + 42.02022 (Nitrogen) = 65.00998928

So the molecular weight of Sodium azide is 65.00998928.
