Ethylenediamine [C2H4(NH2)2] Molecular Weight Calculation

The molecular weight of Ethylenediamine [C2H4(NH2)2] is 60.09888.

Ethylenediamine [C2H4(NH2)2] Molecular Weight CalculationEthylenediamine (C2H4(NH2)2) is an organic compound of three elements: Carbon, Hydrogen, and Nitrogen. The molecular weight of Ethylenediamine is 60.09888 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Ethylenediamine  [C2H4(NH2)2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Ethylenediamine molecule.
From the chemical formula, you will know different atoms and their number in an Ethylenediamine molecule. The chemical formula of Ethylenediamine is C2H4(NH2)2. From the chemical formula of Ethylenediamine, you can find that one molecule of Ethylenediamine consists of two Carbon (C) atoms, eight Hydrogen (H) atoms, and two Nitrogen (N) atoms.

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

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Hydrogen (H): 1.008 (Ref: Lanl-1)

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

Step 3: Calculate the total weight of each atom in a Ethylenediamine molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Ethylenediamine: 2
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Ethylenediamine: 12.0107 x 2 = 24.0214

Number of Hydrogen atoms in Ethylenediamine: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Ethylenediamine: 1.008 x 8 = 5.04

Number of Nitrogen atoms in Ethylenediamine: 2
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Ethylenediamine: 14.00674 x 2 = 28.01348

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

Molecular weight of Ethylenediamine: 24.0214 (Carbon) + 8.064 (Hydrogen) + 28.01348 (Nitrogen) = 60.09888

So the molecular weight of Ethylenediamine is 60.09888.
