Hexane [C6H14] Molecular Weight Calculation

The molecular weight of Hexane (C6H14) is 86.1762.

Hexane [C6H14] Molecular Weight CalculationHexane (C6H14) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Hexane is 86.1762 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Hexane  [C6H14] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in a Hexane molecule.
You will know different atoms and their number in a Hexane molecule from the chemical formula. The chemical formula of Hexane is C6H14. The chemical formula shows that one Hexane molecule consists of six Carbon (C) atoms and fourteen 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 Hexane molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Hexane: 6
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Hexane: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Hexane: 14
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Hexane: 1.008 x 14 = 14.112

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

Molecular weight of Hexane: 72.0642 (Carbon) + 14.112 (Hydrogen) = 86.1762

So the molecular weight of Hexane is 86.1762.
