The molecular weight of Aluminium formate [Al(HCOO)₃] is 162.0340384.

Aluminium formate [Al(HCOO)₃] is an organic compound of four elements: Aluminium, Hydrogen, Carbon, and Oxygen. The molecular weight of Aluminium formate is 162.0340384 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Aluminium formate [Al(HCOO)₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminium formate molecule.
From the chemical formula, you will know different atoms and their number in an Aluminium formate molecule. The chemical formula of Aluminium formate is Al(HCOO)₃. From the chemical formula, you can find that one molecule of Aluminium formate has one Aluminium (Al) atom, three Hydrogen (H) atoms, three Carbon atoms, and six Oxygen (O) 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 Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

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

Number of Hydrogen atoms in Aluminium formate: 3
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Aluminium formate: 1.008 x 3 = 3.024

Number of Carbon atoms in Aluminium formate: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Aluminium formate: 12.0107 x 3 = 36.0321

Number of Oxygen atoms in Aluminium formate: 6
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Aluminium formate: 15.9994 x 6 = 95.9964

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

Molecular weight of Aluminium formate: 26.9815384 (Aluminium) + 3.024 (Hydrogen) + 36.0321 (Carbon) + 95.9964 (Oxygen) = 162.0340384

So the molecular weight of Aluminium formate is 162.0340384.
