The molecular weight of Diketene (C4H4O2) is 84.0736.
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: Diketene (C4H4O2) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Diketene molecule.
From the chemical formula, you will know different atoms and their number in a Diketene molecule. Chemical formula of Diketene is C2H4O2. From the chemical formula of Diketene, you can find that one molecule of Diketene has four Carbon (C) atoms, four Hydrogen (H) atoms and two Oxygen (O) atoms.
Step 2: Find out atomic weights of each atom (from periodic table).
Step 3: Calculate the total weight of each atom present in a Diketene molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Diketene: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Diketene: 12.0107 x 4 = 48.0428
Number of Hydrogen atoms in Diketene: 4
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Diketene: 1.008 x 4 = 4.032
Number of Oxygen atoms in Diketene: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Diketene: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of Diketene by adding up the total weight of all atoms.
Molecular weight of Diketene: 48.0428 (Carbon) + 4.032 (Hydrogen) + 31.9988 (Oxygen) = 84.0736
So the molecular weight of Diketene is 84.0736.
