# Glycidol [C3H6O2] Molecular Weight Calculation

The molecular weight of Glycidol [C3H6O2] is 74.0789.

To calculate molecular weight of any compound, the first step is to know the constituent atoms and their number in that particular compound. Then calculate the total weight of each atom by multiplying its atomic weight by its number. The sum of total weight of all constituent atoms will be the molecular weight of the compound. Note that the value of atomic weight may differ slightly from different sources.

# CALCULATION PROCEDURE: Glycidol [C3H6O2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Glycidol molecule.
From the chemical formula, you will know different atoms and their number in a Glycidol molecule. Chemical formula of Glycidol is C3H6O2. From the chemical formula of Glycidol, you can find that one molecule of Glycidol has three Carbon (C) atoms, six Hydrogen (H) atoms and two 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 Glycidol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Glycidol: 3
Atomic weight of
Carbon (C): 12.0107
Total weight of Carbon atoms in Glycidol: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Glycidol: 6
Atomic weight of
Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Glycidol: 1.008 x 6 = 6.048

Number of Oxygen atoms in Glycidol: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Glycidol: 15.9994 x 2 = 31.9988

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

Molecular weight of Glycidol: 36.0321 (Carbon) + 6.048 (Hydrogen) + 31.9988 (Oxygen) = 74.0789

So the molecular weight of Glycidol is 74.0789.
