The molecular weight of Ascorbic acid [C6H8O6] is 176.1246.

Ascorbic acid [C6H8O6] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Ascorbic acid is 176.1246 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Carbon, Hydrogen, and Oxygen.

CALCULATION PROCEDURE: Ascorbic acid [C6H8O6] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Ascorbic acid molecule.
From the chemical formula, you will know different atoms and their number in an Ascorbic acid molecule. The chemical formula of Ascorbic acid is C6H8O6. From the chemical formula, you can find that one molecule of Ascorbic acid has six Carbon (C) atoms, eight Hydrogen (H) atoms, and six 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 in an Ascorbic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Ascorbic acid: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Ascorbic acid: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Ascorbic acid: 8
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Ascorbic acid: 1.008 x 8 = 8.064

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

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

Molecular weight of Ascorbic acid: 72.0642 (Carbon) + 8.064 (Hydrogen) + 95.9964 (Oxygen) = 176.1246

So the molecular weight of Ascorbic acid is 176.1246.
