Aluminum Phosphate [AlPO4] Molecular Weight Calculation

The molecular weight of Aluminum phosphate [AlPO4] is 121.9529.

Aluminum Phosphate [APlO4] Molecular Weight CalculationAluminum phosphate (AlPO4) is an inorganic compound of three elements: Aluminum, Phosphorus, and Oxygen. The molecular weight of Aluminum phosphate is 121.9529 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Aluminum, Phosphorus, and Oxygen.

 

CALCULATION PROCEDURE: Aluminum phosphate [AlPO4] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in an Aluminum phosphate molecule.
From the chemical formula, you will know different atoms and their number in an Aluminum phosphate molecule. The chemical formula of Aluminum phosphate is AlPO4. From the chemical formula, you can find that one molecule of Aluminum phosphate consists of one Aluminum (Al) atom, one Phosphorus (P) atom, and four Oxygen (O) atoms.

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

Atomic weight of Aluminum (Al): 26.9815384 (Ref: ciaaw-aluminium)
Atomic weight of Phosphorus (P): 30.973761998 (Ref: Jlab-ele015)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

Number of Aluminum atoms in Aluminum phosphate: 1
Atomic weight of Aluminum: 26.9815384
Total weight of Aluminum atoms in Aluminum phosphate: 26.9815384 x 1 = 26.9815384

Number of Phosphorus atoms in Aluminum phosphate: 1
Atomic weight of Phosphorus (P): 30.973761998
Total weight of Phosphorus atoms in Aluminum phosphate: 30.973761998 x 1 = 30.973761998

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

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

Molecular weight of Aluminum phosphate: 26.9815384 (Aluminum) + 30.973761998 (Phosphorus) + 63.9976 (Oxygen) = 121.9529

So the molecular weight of Aluminum phosphate is 121.9529.
