The molecular weight of 2-Propene-1,1-diol [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: 2-Propene-1,1-diol [C3H6O2] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a 2-Propene-1,1-diol molecule.
From the chemical formula, you will know different atoms and their number in a 2-Propene-1,1-diol molecule. Chemical formula of 2-Propene-1,1-diol is C3H6O2. From the chemical formula of 2-Propene-1,1-diol, you can find that one molecule of 2-Propene-1,1-diol 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 2-Propene-1,1-diol molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in 2-Propene-1,1-diol: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in 2-Propene-1,1-diol: 12.0107 x 3 = 36.0321
Number of Hydrogen atoms in 2-Propene-1,1-diol: 6
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in 2-Propene-1,1-diol: 1.008 x 6 = 6.048
Number of Oxygen atoms in 2-Propene-1,1-diol: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in 2-Propene-1,1-diol: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of 2-Propene-1,1-diol by adding up the total weight of all atoms.
Molecular weight of 2-Propene-1,1-diol: 36.0321 (Carbon) + 6.048 (Hydrogen) + 31.9988 (Oxygen) = 74.0789
So the molecular weight of 2-Propene-1,1-diol is 74.0789.
