The molecular weight of Aluminium Fluoride [AlF₃] is 83.976747889.

Aluminium Fluoride [AlF₃] is an inorganic compound of two elements: Aluminium and Fluorine. The molecular weight of Aluminium fluoride [AlF₃] is 83.976747889 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Aluminium Fluoride [AlF₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminium Fluoride molecule.
From the chemical formula, you will know different atoms and their number in an Aluminium fluoride molecule. The chemical formula of Aluminium fluoride is [AlF₃]. From the chemical formula, you can find that one molecule of Aluminium fluoride consists of one Aluminium (Al) atom and three Fluorine (F) 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 Fluorine (F): 18.998403163 (Ref: Pubchem-9, Ciaaw-fluorine)

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

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

Number of Fluorine (F) atoms in Aluminium Fluoride: 3
Atomic weight of Fluorine: 18.99840316
Total weight of Fluorine atoms in Aluminium Fluoride: 18.99840316 x 3 = 56.99520949

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

Molecular weight of Aluminium Fluoride: 26.9815384 (Aluminium) + 56.99520949 (Fluorine) = 83.976747889

So the molecular weight of Aluminium Fluoride is 83.976747889.
