The molecular weight of Dihydroxymalonic acid [C₃H₄O₆] is 136.0605.

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: Dihydroxymalonic acid [C₃H₄O₆] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Dihydroxymalonic acid molecule.
From the chemical formula, you will know different atoms and their number in a Dihydroxymalonic acid molecule. Chemical formula of Dihydroxymalonic acid is C₃H₄O₆. From the chemical formula of Dihydroxymalonic acid, you can find that one molecule of Dihydroxymalonic acid has three Carbon (C) atoms, four Hydrogen (H) atoms and six 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 Dihydroxymalonic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Dihydroxymalonic acid: 3
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Dihydroxymalonic acid: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Dihydroxymalonic acid: 4
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Dihydroxymalonic acid: 1.008 x 4 = 4.032

Number of Oxygen atoms in Dihydroxymalonic acid: 6
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Dihydroxymalonic acid: 15.9994 x 6 = 95.9964

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

Molecular weight of Dihydroxymalonic acid: 36.0321 (Carbon) + 4.032 (Hydrogen) + 95.9964 (Oxygen) = 136.0605

So the molecular weight of Dihydroxymalonic acid is 136.0605.
