# Silver Sulfide [Ag2S] Molecular Weight Calculation

The molecular weight of Silver sulfide [Ag2S] is 247.8024.

Silver sulfide [Ag2S] is an inorganic compound of two elements: Silver and Sulfur. The molecular weight of Silver sulfide is 247.8024 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver and Sulfur.

CALCULATION PROCEDURE: Silver sulfide [Ag2S] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Silver sulfide molecule.
From the chemical formula, you will know different atoms and their number in a Silver sulfide molecule. The chemical formula of Silver sulfide is Ag2S. From the chemical formula, you can find that one molecule of Silver sulfide has two Silver (Ag) atoms and one Sulfur (S) 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 Sulfur (S): 32.066 (Ref: Jlab-ele016)

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

Number of Silver atoms in Silver sulfide: 2
Atomic weight of Silver: 107.8682
Total weight of Silver atoms in Silver sulfide: 107.8682 x 2 = 215.7364

Number of Sulfur atoms in Silver sulfide: 1
Atomic weight of Sulfur: 32.066
Total weight of Sulfur atoms in Silver sulfide: 32.066 x 1 = 32.066

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

Molecular weight of Silver sulfide [Ag2S]: 215.7364 (Silver) + 32.066 (Sulfur) = 247.8024

So the molecular weight of Silver sulfide is 247.8024.
