The molecular weight of Silver chloride [AgCl] is 143.3209.

Silver chloride [AgCl] is an inorganic compound of two elements: Silver and Chlorine. The molecular weight of Silver chloride is 143.3209 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver and Chlorine.

CALCULATION PROCEDURE: Silver chloride [AgCl] Molecular Weight Calculation

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

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

Atomic weight of Silver (Ag): 107.8682 (Ref: Jlab-ele047, ciaaw-silver)
Atomic weight of Chlorine (Cl): 35.4527 (Ref: Pubchem-Chlorine)

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

Number of Silver atoms in Silver chloride: 1
Atomic weight of Silver: 107.8682
Total weight of Silver atoms in Silver chloride: 107.8682 x 1 = 107.8682

Number of Chlorine atoms in Silver chloride: 1
Atomic weight of Chlorine: 35.4527
Total weight of Chlorine atoms in Silver chloride: 35.4527 x 1 = 35.4527

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

Molecular weight of Silver chloride (AgCl): 107.8682 (Silver) + 35.4527 (Chlorine) = 143.3209

So the molecular weight of Silver chloride is 143.3209.
