The molecular weight of Glyoxal (OHCCHO) is 58.0362.
Glyoxal (OHCCHO) is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Glyoxal is 58.0362 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Glyoxal (OHCCHO) Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in a Glyoxal molecule.
You will know different atoms and their number in a Glyoxal molecule from the chemical formula. The chemical formula of Glyoxal is C2H2O2. From the chemical formula, you can find that one molecule of Glyoxal has two Carbon (C) atoms, two Hydrogen (H) atoms, and two Oxygen (O) atoms.
Step 2: Find out the atomic weights of each atom (from the 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 Glyoxal molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Glyoxal: 2
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Glyoxal: 12.0107 x 2 = 24.0214
Number of Hydrogen atoms in Glyoxal: 2
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Glyoxal: 1.008 x 2 = 2.016
Number of Oxygen atoms in Glyoxal: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Glyoxal: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of Glyoxal by adding up the total weight of all atoms.
Molecular weight of Glyoxal: 24.0214 (Carbon) + 2.016 (Hydrogen) + 31.9988 (Oxygen) = 58.0362
So the molecular weight of Glyoxal is 58.0362.
