Potassium Cyanate [KOCN] Molecular Weight Calculation

The molecular weight of Potassium cyanate (KOCN) is 81.11514.

Potassium cyanate (KOCN) Molecular Weight CalculationPotassium cyanate (KOCN) is an organic compound of four elements: Potassium, Oxygen, Carbon, and Nitrogen. The molecular weight of Potassium cyanate (KOCN) is 81.11514 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Potassium, Oxygen, Carbon, and Nitrogen.

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, you can find that one molecule of Potassium cyanate consists of 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: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Potassium cyanate: 15.9994 x 1 = 15.9994

Number of Carbon (C) atoms in Potassium cyanate: 1
Atomic weight of Potassium: 12.0107
Total weight of Carbon atoms in Potassium cyanate: 12.0107 x 1 = 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.
