Tantalum Trialuminide [TaAl3] Molecular Weight Calculation

The molecular weight of Tantalum trialuminide [TaAl3] is 261.8924952.

Tantalum Trialuminide [TaAl3] Molecular Weight CalculationTantalum trialuminide [TaAl3] (CAS Number: 12004-76-1) is an inorganic compound of two elements: Aluminium and Tantalum. The molecular weight of Tantalum trialuminide is 261.8924952 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Tantalum trialuminide [TaAl3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Tantalum trialuminide molecule.
From the chemical formula, you will know different atoms and their number in a Tantalum trialuminide molecule. The chemical formula of Tantalum trialuminide is TaAl3. From the chemical formula, you can find that one molecule of Tantalum trialuminide has one Tantalum (Ta) atom and three Aluminium (Al) atoms.

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

Atomic weight of Aluminium (Al): 80.9446152 (Ref: Jlab-ele073, ciaaw-tantalum, Nist-73)
Atomic weight of Tantalum (Ta): 180.94788 (Ref: Jlab-ele006)

Step 3: Calculate the total weight of each atom in a Tantalum trialuminide molecule by multiplying its atomic weight by its number.

Number of Tantalum atoms in Tantalum trialuminide: 1
Atomic weight of Tantalum: 180.94788
Total weight of Tantalum atoms in Tantalum trialuminide: 180.94788 x 1 = 180.94788

Number of Aluminium atoms in Tantalum trialuminide: 3
Atomic weight of Aluminium: 26.9815384
Total weight of Aluminium atoms in Tantalum trialuminide: 26.9815384 x 3 = 80.9446152

Step 4: Calculate the molecular weight of Tantalum trialuminide by adding up the total weight of all atoms.

Molecular weight of Tantalum trialuminide: 80.9446152 (Aluminium) + 180.94788 (Tantalum) = 261.8924952

So the molecular weight of Tantalum trialuminide is 261.8924952.
