**CALCULATION PROCEDURE: Potassium cyanate [KOCN] Molecular Weight Calculation**

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Potassium cyanate molecule. **From the chemical formula, you will know different atoms and their number in a Potassium cyanate molecule. Chemical formula of Potassium cyanate is KOCN. From the chemical formula of Potassium cyanate, you can find that one molecule of Potassium cyanate has one Potassium (K) atom, Oxygen (O) atom, one Carbon (C) atoms, and one Nitrogen (H) atom.

**Step 2: Find out atomic weights of each atom (from periodic table). **

Atomic weight of Potassium (K): 39.0983 (Ref: Ciaaw-potassium)

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

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)

Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)

**Step 3: Calculate the molecular weight of Potassium cyanate by adding the total weight of all atoms. **

Number of Potassium (K) atoms in Potassium cyanate: 1

Atomic weight of Potassium: 39.0983

Total weight of Potassium atoms in Potassium cyanate: 39.0983 x 1 = 39.0983

Number of Oxygen (O) atoms in Potassium cyanate: 4

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Potassium cyanate: 15.9994 x 4 = 15.9994

Number of Carbon (C) atoms in Potassium cyanate: 4

Atomic weight of Potassium: 12.0107

Total weight of Carbon atoms in Potassium cyanate: 12.0107 x 4 = 12.0107

Number of Nitrogen (N) atoms in Potassium cyanate: 1

Atomic weight of Nitrogen: 14.00674

Total weight of Nitrogen atoms in Potassium cyanate: 14.00674 x 1 = 14.00674

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

Molecular weight of Potassium cyanate : 39.0983 (Potassium) + 15.9994 (Oxygen) + 12.0107 (Carbon) + 14.00674 (Nitrogen)

So the molecular weight of Potassium cyanate is 81.11514.
