Nonane [C9H20] Molecular Weight Calculation

The molecular weight of Nonane (C9H20) is 128.2563.

Nonane [C9H20] Molecular Weight CalculationNonane (C9H20) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Nonane is 128.2563 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Nonane  [C9H20] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in a Nonane molecule.
You will know different atoms and their number in a Nonane molecule from the chemical formula. The chemical formula of Nonane is C9H20. The chemical formula shows that one Nonane molecule consists of nine Carbon (C) atoms and twenty 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 Nonane molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Nonane: 9
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Nonane: 12.0107 x 9 = 108.0963

Number of Hydrogen atoms in Nonane: 20
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Nonane: 1.008 x 20 = 20.16

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

Molecular weight of Nonane: 108.0963 (Carbon) + 20.16 (Hydrogen) = 128.2563

So the molecular weight of Nonane is 128.2563.
