Aluminium nitride [AlN] is an inorganic compound of two elements: Aluminium and Nitrogen. The molecular weight of Aluminium nitride [AlN] is 40.9882784 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Aluminium Nitride [AlN] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminium nitride molecule.
From the chemical formula, you will know different atoms and their number in an Aluminium nitride molecule. The chemical formula of Aluminium nitride is AlN. From the chemical formula, you can find that one molecule of Aluminium nitride consists of one Aluminium (Al) atom and one Nitrogen (N) atom.

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

Atomic weight of Aluminium (Al): 26.9815384 (Ref: ciaaw-aluminium)
Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)

Step 3: Calculate the molecular weight of Aluminium nitride by adding the total weight of all atoms.

Number of Aluminium atoms in Aluminium nitride: 1
Atomic weight of Aluminium: 26.9815384
Total weight of Aluminium atoms in Aluminium nitride: 26.9815384 x 1 = 26.9815384

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

Step 4: Calculate the molecular weight of Aluminium nitride by adding up the total weight of all atoms.

Molecular weight of Aluminium nitride: 26.9815384 (Aluminium) + 14.00674 (Nitrogen) = 40.9882784

So the molecular weight of Aluminium nitride is 40.9882784.
