# Silver Selenide [Ag2Se] Molecular Weight Calculation

The molecular weight of Silver selenide [Ag2Se] is 294.7074.

Silver selenide [Ag2Se] is an inorganic compound of three elements: Silver and Selenium. The molecular weight of Silver selenide is 294.7074 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver and Selenium.

CALCULATION PROCEDURE: Silver selenide [Ag2Se] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Silver selenide molecule.
From the chemical formula, you will know different atoms and their number in a Silver selenide molecule. The chemical formula of Silver selenide is Ag2Se. From the chemical formula, you can find that one molecule of Silver selenide has two Silver (Ag) atoms and one Selenium (Se) 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 Selenium (Se): 78.971 (Ref: Jlab-ele034, ciaaw-selenium)

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

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

Number of Selenium atoms in Silver selenide: 1
Atomic weight of Selenium: 78.971
Total weight of Selenium atoms in Silver selenide: 78.971 x 1 = 78.971

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

Molecular weight of Silver selenide [Ag2Se]: 215.7364 (Silver) + 78.971 (Selenium) = 294.7074

So the molecular weight of Silver selenide is 294.7074.
