# Decane [C10H22] Molecular Weight Calculation

The molecular weight of Decane (C10H22) is 142.283. Decane (C10H22) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Decane is 142.283 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Decane  [C10H22] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in a Decane molecule.
You will know different atoms and their number in a Decane molecule from the chemical formula. The chemical formula of Decane is C10H22. The chemical formula shows that one Decane molecule consists of ten Carbon (C) atoms and twenty-two 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 Decane molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Decane: 10
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Decane: 12.0107 x 10 = 120.107

Number of Hydrogen atoms in Decane: 22
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Decane: 1.008 x 22 = 22.176

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

Molecular weight of Decane: 120.107 (Carbon) + 22.176 (Hydrogen) = 142.283

So the molecular weight of Decane is 142.283.
