The molecular weight of Aluminium carbide [Al₄C₃] is 143.9582536.

Aluminium carbide [Al₄C₃] (CAS Number: 1299-86-1) is an organic compound of two elements: Aluminium and Carbon. The molecular weight of Aluminium carbide is 143.9582536 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Aluminium Carbide [Al₄C₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminium carbide molecule.
From the chemical formula, you will know different atoms and their number in an Aluminium carbide molecule. The chemical formula of Aluminium carbide is Al₄C₃. From the chemical formula, you can find that one molecule of Aluminium carbide has four Aluminium (Al) atoms and three Carbon (C) atoms.

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

Atomic weight of Aluminium (Al): 107.9261536 (Ref: ciaaw-aluminium)
Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)

Step 3: Calculate the total weight of each atom in an Aluminium carbide molecule by multiplying its atomic weight by its number.

Number of Aluminium atoms in Aluminium carbide: 4
Atomic weight of Aluminium: 26.9815384
Total weight of Aluminium atoms in Aluminium carbide: 26.9815384 x 4 = 107.9261536

Number of Carbon atoms in Aluminium carbide: 3
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Aluminium carbide: 12.0107 x 3 = 36.0321

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

Molecular weight of Aluminium carbide: 107.9261536 (Aluminium) + 36.0321 (Carbon) = 143.9582536

So the molecular weight of Aluminium carbide is 143.9582536.
