# Calcium Aluminate [CaAl2O4] Molecular Weight Calculation

The molecular weight of Calcium aluminate [CaAl2O4] is 158.0386768.

Calcium aluminate [CaAl2O4] (CAS Registry Number: 12042-68-1) is an inorganic compound of three elements: Calcium (Ca), Aluminium (Al), and Oxygen (O). The molecular weight of Calcium aluminate [CaAl2O4] is 158.0386768 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Calcium Aluminate [CaAl2O4] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Calcium aluminate molecule.
From the chemical formula, you will know different atoms and their number in a Calcium aluminate molecule. The chemical formula of Calcium aluminate is CaAl2O4. From the chemical formula, you can find that one molecule of Calcium aluminate consists of one Calcium (Ca) 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 Calcium (Ca): 40.078 (Ref: Pubchem-20, Ciaaw-calcium)
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 Calcium aluminate by adding the total weight of all atoms.

Number of Calcium (Ca) atoms in Calcium aluminate: 1
Atomic weight of Calcium: 40.078
Total weight of Calcium atoms in Calcium aluminate: 40.078 x 1 = 40.078

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

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

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

Molecular weight of Calcium aluminate: 40.078 (Calcium) + 53.9630768 (Aluminium) + 63.9976 (Oxygen) = 158.0386768

So the molecular weight of Calcium aluminate is 158.0386768.
