The molecular weight of Strontium aluminate [SrAl₂O₄] is 205.5806768.

Strontium aluminate [SrAl₂O₄] (CAS Registry Number: 12004-37-4) is an inorganic compound of three elements: Strontium (Sa), Aluminium (Al), and Oxygen (O). The molecular weight of Strontium aluminate [SrAl₂O₄] is 205.5806768 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Strontium Aluminate [SrAl₂O₄] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Strontium aluminate molecule.
From the chemical formula, you will know different atoms and their number in a Strontium aluminate molecule. The chemical formula of Strontium aluminate is SrAl₂O₄. From the chemical formula, you can find that one molecule of Strontium aluminate consists of one Strontium (Sr) atom, two Aluminium (Al) atoms, and four Oxygen (O) atoms.

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

Atomic weight of Strontium (Sr): 87.62 (Ref: Jlab-ele038, Lanl-38, Ciaaw-strontium)
Atomic weight of Aluminium (Al): 26.9815384 (Ref: ciaaw-aluminium)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

Step 3: Calculate the molecular weight of Strontium aluminate by adding the total weight of all atoms.

Number of Strontium (Sr) atoms in Strontium aluminate: 1
Atomic weight of Strontium: 87.62
Total weight of Strontium atoms in Strontium aluminate: 87.62 x 1 = 87.62

Number of Aluminium atoms in Strontium aluminate: 2
Atomic weight of Aluminium: 26.9815384
Total weight of Aluminium atoms in Strontium aluminate: 26.9815384 x 2 = 53.9630768

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

Step 4: Calculate the molecular weight of Strontium aluminate by adding up the total weight of all atoms.

Molecular weight of Strontium aluminate: 87.62 (Strontium) + 53.9630768 (Aluminium) + 63.9976 (Oxygen) = 205.5806768

So the molecular weight of Strontium aluminate is 205.5806768.
