The molecular weight of Heptadecane (C₁₇H₃₆) is 240.4699.

Heptadecane (C₁₇H₃₆) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Heptadecane is 240.4699 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Heptadecane  [C₁₇H₃₆] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in a Heptadecane molecule.
You will know different atoms and their number in a Heptadecane molecule from the chemical formula. The chemical formula of Heptadecane is C₁₇H₃₆. The chemical formula shows that one Heptadecane molecule consists of seventeen Carbon (C) atoms and thirty-six Hydrogen (H) 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)

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

Number of Carbon atoms in Heptadecane: 17
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Heptadecane: 12.0107 x 17 = 204.1819

Number of Hydrogen atoms in Heptadecane: 36
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Heptadecane: 1.008 x 36 = 36.288

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

Molecular weight of Heptadecane: 204.1819 (Carbon) + 36.288 (Hydrogen) = 240.4699

So the molecular weight of Heptadecane is 240.4699.
