The molecular weight of Aluminum acetate dibasic is 120.0405384 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Aluminum, Carbon, Hydrogen, and Oxygen.

CALCULATION PROCEDURE: Aluminum acetate dibasic [CH3COOAl(OH)₂] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminum acetate dibasic molecule.
You will know different atoms and their number in an Aluminum acetate dibasic molecule from the chemical formula. The chemical formula of Aluminum acetate dibasic is [CH3COOAl(OH)₂]. From the chemical formula, you can find that one molecule of Aluminum acetate dibasic has two Carbon (C) atoms, five Hydrogen (H) atoms, four Oxygen (O) atoms, and one Aluminum (Al) atom.

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

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)
Atomic weight of Aluminum (Al): 26.9815384 (Ref: ciaaw-aluminium)

Step 3: Calculate the total weight of each atom in an Aluminum acetate dibasic molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Aluminum acetate dibasic: 2
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Aluminum acetate dibasic: 12.0107 x 2 = 24.0214

Number of Hydrogen atoms in Aluminum acetate dibasic: 5
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Aluminum acetate dibasic: 1.008 x 4 = 5.04

Number of Oxygen atoms in Aluminum acetate dibasic: 4
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Aluminum acetate dibasic: 15.9994 x 5 = 63.9976

Number of Aluminum atoms in Aluminum acetate dibasic: 1
Atomic weight of Aluminum (Al): 26.9815384
Total weight of Aluminum atoms in Aluminum acetate dibasic: 26.9815384 x 1 = 26.9815384

Step 4: Calculate the molecular weight of Aluminum acetate dibasic by adding up the total weight of all atoms.

Molecular weight of Aluminum acetate dibasic: 24.0214 (Carbon) + 5.04 (Hydrogen) + 63.9976 (Oxygen) + 26.9815384 (Aluminum) = 120.0405384

So the molecular weight of Aluminum acetate dibasic is 120.0405384.
