# Lithium Aluminate [LiAlO2] Molecular Weight Calculation

The molecular weight of Lithium aluminate [LiAlO2] is 65.9213384.

Lithium aluminate [LiAlO2] (CAS Registry Number: 12003-67-7) is an inorganic compound of three elements: Lithium (Li), Aluminium (Al), and Oxygen (O). The molecular weight of Lithium aluminate [LiAlO2] is 65.9213384 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Lithium aluminate [LiAlO2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Lithium aluminate molecule.
From the chemical formula, you will know different atoms and their number in a Lithium aluminate molecule. The chemical formula of Lithium aluminate is LiAlO2. From the chemical formula, you can find that one molecule of Lithium aluminate consists of one Lithium (Li) atom, one Aluminium (Al) atom, and two Oxygen (O) atoms.

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

Atomic weight of Lithium (Li): 6.941 (Ref: jlab-ele003)
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 Lithium aluminate by adding the total weight of all atoms.

Number of Lithium (Li) atoms in Lithium aluminate: 1
Atomic weight of Lithium: 6.941
Total weight of Lithium atoms in Lithium aluminate: 6.941 x 1 = 6.941

Number of Aluminium atoms in Lithium aluminate: 1
Atomic weight of Aluminium: 26.9815384
Total weight of Aluminium atoms in Lithium aluminate: 26.9815384 x 1 = 26.9815384

Number of Oxygen (O) atoms in Lithium aluminate: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Lithium aluminate: 15.9994 x 2 = 31.9988

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

Molecular weight of Lithium aluminate: 6.941 (Lithium) + 26.9815384 (Aluminium) + 31.9988 (Oxygen) = 65.9213384

So the molecular weight of Lithium aluminate is 65.9213384.
