The molecular weight of Undecane (C11H24) is 156.3097.
Undecane (C11H24) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Undecane is 156.3097 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Undecane [C11H24] Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in an Undecane molecule.
You will know different atoms and their number in an Undecane molecule from the chemical formula. The chemical formula of Undecane is C11H24. The chemical formula shows that one Undecane molecule consists of eleven Carbon (C) atoms and twenty-four 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 an Undecane molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Undecane: 11
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Undecane: 12.0107 x 11 = 132.1177
Number of Hydrogen atoms in Undecane: 24
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Undecane: 1.008 x 24 = 24.192
Step 4: Calculate the molecular weight of Undecane by adding up the total weight of all atoms.
Molecular weight of Undecane: 132.1177 (Carbon) + 24.192 (Hydrogen) = 156.3097
So the molecular weight of Undecane is 156.3097.
