Endrin (C12H8Cl6O) is an organic compound of four elements: Carbon, Hydrogen, Chlorine, and Oxygen. The molecular weight of Endrin is 380.908 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Endrin  [C12H8Cl6O] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Endrin molecule.
You will know different atoms and their number in an Endrin molecule from the chemical formula. The chemical formula of Endrin is C12H8Cl6O. The chemical formula shows that one molecule of Endrin consists of twelve Carbon (C) atoms, eight Hydrogen (H) atoms, six Chlorine atoms, and one Oxygen atom.

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 Chlorine (Cl): 35.4527 (Ref: jlab-ele017)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

Number of Carbon atoms in Endrin: 12
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Endrin: 12.0107 x 12 = 144.1284

Number of Hydrogen atoms in Endrin: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Endrin: 1.008 x 8 = 8.064

Number of Chlorine atoms in Endrin: 6
Atomic weight of Chlorine (Cl): 35.4527
Total weight of Chlorine atoms in Endrin: 35.4527 x 6 = 212.7162

Number of Oxygen atoms in Endrin: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Endrin: 15.9994 x 1 = 15.9994

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

Molecular weight of Endrin: 144.1284 (Carbon) + 8.064 (Hydrogen) + 212.7162 (Chlorine) + 15.9994 (Oxygen) = 380.908

So the molecular weight of Endrin is 380.908.
