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.
