The molecular weight of Glycerol (C3H8O3) is 92.0943.
Glycerol (C3H8O3) is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Glycerol is 92.0943 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Glycerol (C3H8O3) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Glycerol molecule.
From the chemical formula, you will know different atoms and their number in a Glycerol molecule. The chemical formula of Glycerol is C3H8O3. From the chemical formula, you can find that one molecule of Glycerol has three Carbon (C) atoms, eight Hydrogen (H) atoms, and three Oxygen (O) atoms.
Step 2: Find out atomic weights of each atom (from periodic table).
Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Hydrogen (H) : 1.008 (Ref: Lanl-1)
Atomic weight of Oxygen (O) : 15.9994 (Ref: Jlab-ele008)
Step 3: Calculate the total weight of each atom present in a Glycerol molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Glycerol: 3
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Glycerol: 12.0107 x 3 = 36.0321
Number of Hydrogen atoms in Glycerol: 8
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Glycerol: 1.008 x 8 = 8.064
Number of Oxygen atoms in Glycerol: 3
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Glycerol: 15.9994 x 3 = 47.9982
Step 4: Calculate the molecular weight of Glycerol by adding up the total weight of all atoms.
Molecular weight of Glycerol: 36.0321 (Carbon) + 8.064 (Hydrogen) + 47.9982 (Oxygen) = 92.0943
So the molecular weight of Glycerol is 92.0943.
