The molecular weight of Barium chloride [BaCl₂] is 208.2324.

Barium chloride [BaCl₂] is an inorganic compound of two elements: Barium and Chlorine. The molecular weight of Barium chloride is 208.2324 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Barium and Chlorine.

CALCULATION PROCEDURE: Barium chloride [BaCl₂] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Barium chloride molecule.
From the chemical formula, you will know different atoms and their number in a Barium chloride molecule. The chemical formula of Barium chloride is BaCl₂. From the chemical formula, you can find that one molecule of Barium chloride has one Barium (Ba) atom and two Chlorine (Cl) atoms.

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

Atomic weight of Barium (Ba): 137.327 (Ref: Pubchem-56, Ciaaw-barium)
Atomic weight of Chlorine (Cl): 35.4527 (Ref: Pubchem-Chlorine, jlab-ele017)

Step 3: Calculate the molecular weight of Barium chloride by adding the total weight of all atoms.

Number of Barium atoms in Barium chloride: 1
Atomic weight of Barium: 137.327
Total weight of Barium atoms in Barium chloride: 137.327 x 1 = 137.327

Number of Chlorine atoms in Barium chloride: 2
Atomic weight of Chlorine: 35.4527
Total weight of Chlorine atoms in Barium chloride: 35.4527 x 2 = 70.9054

Step 4: Calculate the molecular weight of Barium chloride by adding up the total weight of all atoms.

Molecular weight of Barium chloride (BaCl₂): 137.327 (Barium) + 70.9054 (Chlorine) = 208.2324

So the molecular weight of Barium chloride is 208.2324.
