The molecular weight of Aluminium diboride [AlB₂] is 48.6035384.

Aluminium diboride [AlB₂] is an inorganic compound of two elements: Aluminium and Boron. The molecular weight of Aluminium diboride is 48.6035384 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Aluminium Diboride [AlB2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminium diboride molecule.
From the chemical formula, you will know different atoms and their number in an Aluminium diboride molecule. The chemical formula of Aluminium diboride is AlB₂. From the chemical formula, you can find that one molecule of Aluminium diboride consists of one Aluminium (Al) atom and two Boron (B) atoms.

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 Boron (B): 10.811 (Ref: Jlab-ele005)

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

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

Number of Boron (B) atoms in Aluminium diboride: 2
Atomic weight of Boron: 10.811
Total weight of Boron in Aluminium diboride: 10.811 x 2 = 21.622

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

Molecular weight of Aluminium diboride: 26.9815384 (Aluminium) + 21.622 (Boron) = 48.6035384

So the molecular weight of Aluminium diboride is 48.6035384.
