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.
