# Strontium Aluminate [SrAl2O4] Molecular Weight Calculation

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.
