The molecular weight of Oxirene (C2H2O) is 42.0368.
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: Oxirene (C2H2O) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Oxirene molecule.
From the chemical formula, you will know different atoms and their number in a Oxirene molecule. Chemical formula of Oxirene is C2H2O. From the chemical formula of Oxirene, you can find that one molecule of Oxirene has two Carbon (C) atoms, two 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 Oxirene molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Oxirene: 2
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Oxirene: 12.0107 x 2 = 24.0214
Number of Hydrogen atoms in Oxirene: 2
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Oxirene: 1.008 x 2 = 2.016
Number of Oxygen atoms in Oxirene: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Oxirene: 15.9994 x 1 = 15.9994
Step 4: Calculate the molecular weight of Oxirene by adding up the total weight of all atoms.
Molecular weight of Oxirene: 24.0214 (Carbon) + 2.016 (Hydrogen) + 15.9994 (Oxygen) = 42.0368
So the molecular weight of Oxirene is 42.0368.
