The molecular weight of Silver dichromate [Ag₂Cr₂O₇] is 431.7244.

Silver dichromate [Ag₂Cr₂O₇] is an inorganic compound of three elements: Silver, Chromium, and Oxygen. The molecular weight of Silver dichromate is 431.7244 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver, Chromium, and oxygen.

CALCULATION PROCEDURE: Silver dichromate [Ag₂Cr₂O₇] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Silver dichromate molecule.
From the chemical formula, you will know different atoms and their number in a Silver dichromate molecule. The chemical formula of Silver dichromate is Ag₂Cr₂O₇. From the chemical formula, you can find that one molecule of Silver dichromate has two Silver (Ag) atoms, two Chromium (Cr) atoms, and seven Oxygen (O) atoms.

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 Chromium (Cr): 51.9961 (Ref: Jlab-ele024, ciaaw-chromium, Nist-24)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

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

Number of Chromium atoms in Silver dichromate: 2
Atomic weight of Chromium: 51.9961
Total weight of Chromium atoms in Silver dichromate: 51.9961 x 2 = 51.9961

Number of Oxygen atoms in Silver dichromate: 7
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Silver dichromate: 15.9994 x 7 = 111.9958

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

Molecular weight of Silver dichromate [Ag₂Cr₂O₇]: 215.7364 (Silver) + 51.9961 (Chromium) + 111.9958 (Oxygen) = 431.7244

So the molecular weight of Silver dichromate is 431.7244.
