**CALCULATION PROCEDURE: Copper(II) Aluminate [CuAl**_{2}O_{4}] Molecular Weight Calculation

_{2}O

_{4}] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Copper aluminate molecule. **From the chemical formula, you will know different atoms and their number in a Copper(II) aluminate molecule. The chemical formula of Copper(II) aluminate is CuAl

_{2}O

_{4}. From the chemical formula, you can find that one molecule of Copper aluminate consists of one Copper (Cu) 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 Copper (Cu): 63.546 (Ref: Jlab-ele029)

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 Copper(II) aluminate by adding the total weight of all atoms. **

Number of Copper (Cu) atoms in Copper(II) aluminate: 1

Atomic weight of Copper: 63.546

Total weight of Copper atoms in Copper(II) aluminate: 63.546 x 1 = 63.546

Number of Aluminium atoms in Copper(II) aluminate: 2

Atomic weight of Aluminium: 26.9815384

Total weight of Aluminium atoms in Copper(II) aluminate: 26.9815384 x 2 = 53.9630768

Number of Oxygen (O) atoms in Copper(II) aluminate: 4

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Copper(II) aluminate: 15.9994 x 4 = 63.9976

**Step 4: Calculate the molecular weight of Copper(II) aluminate by adding up the total weight of all atoms. **

Molecular weight of Copper(II) aluminate: 63.546 (Copper) + 53.9630768 (Aluminium) + 63.9976 (Oxygen) = 181.5066768

So the molecular weight of Copper(II) aluminate is 181.5066768.
