Heptachlor (C10H5Cl7) is an organic compound of three elements: Carbon, Hydrogen, and Chlorine. The molecular weight of Heptachlor is 373.3159 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Heptachlor [C10H5Cl7] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Heptachlor molecule.
You will know different atoms and their number in a Heptachlor molecule from the chemical formula. The chemical formula of Heptachlor is C10H5Cl7. The chemical formula shows that one molecule of Heptachlor consists of ten Carbon (C) atoms, five Hydrogen (H) atoms, and seven Chlorine atoms.
Step 2: Find out the atomic weights of each atom (from the periodic table).
Step 3: Calculate the total weight of each atom in a Heptachlor molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Heptachlor: 10
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Heptachlor: 12.0107 x 10 = 120.107
Number of Hydrogen atoms in Heptachlor: 5
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Heptachlor: 1.008 x 5 = 5.04
Number of Chlorine atoms in Heptachlor: 7
Atomic weight of Chlorine (Cl): 35.4527
Total weight of Chlorine atoms in Heptachlor: 35.4527 x 7 = 248.1689
Step 4: Calculate the molecular weight of Heptachlor by adding up the total weight of all atoms.
Molecular weight of Heptachlor: 120.107 (Carbon) + 5.04 (Hydrogen) + 248.1689 (Chlorine) = 373.3159
So the molecular weight of Heptachlor is 373.3159.
