The molecular weight of Silver nitrate [AgNO_{3}] is 169.87314.

Silver nitrate [AgNO_{3}] is an inorganic compound of three elements: Silver, Nitrogen, and Oxygen. The molecular weight of Silver nitrate is 169.87314 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver, Nitrogen, and oxygen.

**CALCULATION PROCEDURE: Silver Nitrate [AgNO _{3}] Molecular Weight Calculation **

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Silver nitrate molecule. **From the chemical formula, you will know different atoms and their number in a Silver nitrate molecule. The chemical formula of Silver nitrate is AgNO

_{3}. From the chemical formula, you can find that one molecule of Silver nitrate has one Silver (Ag) atom, one Nitrogen (N) atom, and three 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 Nitrogen (N): 14.00674 (Ref: Jlab-ele007)

Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

Number of Silver (Ag) atoms in Silver nitrate: 1

Atomic weight of Silver: 107.8682

Total weight of Silver atoms in Silver nitrate: 107.8682 x 1 = 107.8682

Number of Nitrogen (N) atoms in Silver nitrate: 1

Atomic weight of Nitrogen: 14.00674

Total weight of Nitrogen atoms in Silver nitrate: 14.00674 x 1 = 14.00674

Number of Oxygen (O) atoms in Silver nitrate: 3

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Silver nitrate: 15.9994 x 3 = 47.9982

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

Molecular weight of Silver nitrate (AgNO_{3}): 107.8682 (Silver) + 14.00674 (Nitrogen) + 47.9982 (Oxygen) = 169.87314

So the molecular weight of Silver nitrate is 169.87314.
