The molecular weight of Pentadecane (C15H32) is 212.4165.
Pentadecane (C15H32) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Pentadecane is 212.4165 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Pentadecane [C15H32] Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in a Pentadecane molecule.
You will know different atoms and their number in a Pentadecane molecule from the chemical formula. The chemical formula of Pentadecane is C15H32. The chemical formula shows that one Pentadecane molecule consists of fifteen Carbon (C) atoms and thirty-two Hydrogen (H) atoms.
Step 2: Find out the atomic weights of each atom (from the periodic table).
Step 3: Calculate the total weight of each atom in a Pentadecane molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Pentadecane: 15
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Pentadecane: 12.0107 x 15 = 180.1605
Number of Hydrogen atoms in Pentadecane: 32
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Pentadecane: 1.008 x 32 = 32.256
Step 4: Calculate the molecular weight of Pentadecane by adding up the total weight of all atoms.
Molecular weight of Pentadecane: 180.1605 (Carbon) + 32.256 (Hydrogen) = 212.4165
So the molecular weight of Pentadecane is 212.4165.
