Vinyl alcohol (CH2CHOH) Molecular Weight Calculation

The molecular weight of Vinyl alcohol (CH2CHOH) is 44.0528.

Vinyl alcohol (CH2CHOH) Molecular Weight CalculationTo 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: Vinyl alcohol (CH2CHOH) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Vinyl alcohol molecule.
From the chemical formula, you will know different atoms and their number in a Vinyl alcohol molecule. Chemical formula of Vinyl alcohol is C2H4O. From the chemical formula of Vinyl alcohol, you can find that one molecule of Vinyl alcohol has two Carbon (C) atoms, four Hydrogen (H) atoms and one Oxygen (O) atom.

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 Vinyl alcohol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Vinyl alcohol: 2
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Vinyl alcohol: 12.0107 x 2 = 24.0214

Number of Hydrogen atoms in Vinyl alcohol: 4
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Vinyl alcohol: 1.008 x 4 = 4.032

Number of Oxygen atoms in Vinyl alcohol: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Vinyl alcohol: 15.9994 x 1 = 15.9994

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

Molecular weight of Vinyl alcohol: 24.0214 (Carbon) + 4.032 (Hydrogen) + 15.9994 (Oxygen) = 44.0528

So the molecular weight of Vinyl alcohol is 44.0528.
