# Glucic Acid (C3H4O3) Molecular Weight Calculation

The molecular weight of Glucic acid (C3H4O3) is 88.0623. 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: Glucic acid (C3H4O3) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Glucic acid molecule.
From the chemical formula, you will know different atoms and their number in a Glucic acid molecule. Chemical formula of Glucic acid is C3H4O3. From the chemical formula of Glucic acid, you can find that one molecule of Glucic acid has three Carbon (C) atoms, four 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 Glucic acid molecule by multiplying its atomic weight by its number.

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

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

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

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

Molecular weight of Glucic acid: 36.0321 (Carbon) + 4.032 (Hydrogen) + 47.9982 (Oxygen) = 88.0623

So the molecular weight of Glucic acid is 88.0623.
