The molecular weight of Aluminium dodecaboride [AlB₁₂] is 156.713538400.

Aluminium dodecaboride [AlB₁₂] is an inorganic compound of two elements: Aluminium and Boron. The molecular weight of Aluminium dodecaboride is 156.713538400 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Aluminium dodecaboride [AlB₁₂] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminium dodecaboride molecule.
From the chemical formula, you will know different atoms and their number in an Aluminium dodecaboride molecule. The chemical formula of Aluminium dodecaboride is AlB₁₂. From the chemical formula, you can find that one molecule of Aluminium dodecaboride consists of one Aluminium (Al) atom and twelve 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 dodecaboride by adding the total weight of all atoms.

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

Number of Boron (B) atoms in Aluminium dodecaboride: 12
Atomic weight of Boron: 10.811
Total weight of Boron in Aluminium dodecaboride: 10.811 x 12 = 129.732

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

Molecular weight of Aluminium dodecaboride: 26.9815384 (Aluminium) + 129.732 (Boron) = 156.713538400

So the molecular weight of Aluminium dodecaboride is 156.713538400.
