The molecular weight of Silver iodate [AgIO_{3}] is 282.77087.

Silver iodate [AgIO_{3}] is an inorganic compound of three elements: Silver, Iodine, and Oxygen. The molecular weight of Silver iodate is 282.77087 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Silver, Iodine, and oxygen.

**CALCULATION PROCEDURE: Silver iodate [AgIO _{3}] Molecular Weight Calculation **

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Silver iodate molecule. **From the chemical formula, you will know different atoms and their number in a Silver iodate molecule. The chemical formula of Silver iodate is AgIO3. From the chemical formula, you can find that one molecule of Silver iodate has one Silver (Ag) atom, one Iodine (I) 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 Iodine (I): 126.90447 (Ref: Jlab-ele053, Ciaaw-iodine, Nist-53)

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

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

Number of Silver atoms in Silver iodate: 1

Atomic weight of Silver: 107.8682

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

Number of Iodine atoms in Silver iodate: 1

Atomic weight of Iodine: 126.90447

Total weight of Iodine atoms in Silver iodate: 126.90447 x 1 = 126.90447

Number of Oxygen atoms in Silver iodate: 3

Atomic weight of Oxygen (O): 15.9994

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

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

Molecular weight of Silver iodate (AgIO_{3}): 107.8682 (Silver) + 126.90447 (Iodine) + 47.9982 (Oxygen) = 282.77087

So the molecular weight of Silver iodate is 282.77087.
