The molecular weight of Paraldehyde [C₆H₁₂O₃] is 132.1584.

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: Paraldehyde [C₆H₁₂O₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Paraldehyde molecule.
From the chemical formula, you will know different atoms and their number in a Paraldehyde molecule. Chemical formula of Paraldehyde is C₆H₁₂O₃. From the chemical formula of Paraldehyde, you can find that one molecule of Paraldehyde has six Carbon (C) atoms, twelve 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 Paraldehyde molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Paraldehyde: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Paraldehyde: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Paraldehyde: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Paraldehyde: 1.008 x 12 = 12.096

Number of Oxygen atoms in Paraldehyde: 3
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Paraldehyde: 15.9994 x 3 = 47.9982

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

Molecular weight of Paraldehyde: 72.0642 (Carbon) + 12.096 (Hydrogen) + 47.9982 (Oxygen) = 132.1584

So the molecular weight of Paraldehyde is 132.1584.
