# Silver Iodide (AgI) Molecular Weight Calculation

The molecular weight of Silver iodide [AgI] is 234.77267.

Silver iodide [AgI] is an inorganic compound of two elements: Silver (Ag) and Iodine (I). The molecular weight of Silver iodide is 234.77267 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver and Iodine.

CALCULATION PROCEDURE: Silver Iodide [AgI] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Silver iodide molecule.
From the chemical formula, you will know different atoms and their number in a Silver iodide molecule. The chemical formula of Silver iodide is AgI. From the chemical formula, you can find that one molecule of Silver iodide has one Silver (Ag) atom and one Iodine (I) 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 Iodine (I): 126.90447 (Ref: Jlab-ele053, Ciaaw-iodine, Nist-53)

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

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

Number of Iodine atoms in Silver iodide: 1
Atomic weight of Iodine: 126.90447
Total weight of Iodine atoms in Silver iodide: 126.90447 x 1 = 126.90447

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

Molecular weight of Silver iodide (AgI): 107.8682 (Silver) + 126.90447 (Iodine) = 234.77267

So the molecular weight of Silver iodide is 234.77267.
