# CALCULATION PROCEDURE: 4-Hydroxy-4-methylpentanoic acid [C6H12O3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a 4-Hydroxy-4-methylpentanoic acid molecule.
From the chemical formula, you will know different atoms and their number in a 4-Hydroxy-4-methylpentanoic acid molecule. Chemical formula of 4-Hydroxy-4-methylpentanoic acid is C6H12O3. From the chemical formula of 4-Hydroxy-4-methylpentanoic acid, you can find that one molecule of 4-Hydroxy-4-methylpentanoic acid has six Carbon (C) atoms, twelve 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 4-Hydroxy-4-methylpentanoic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in 4-Hydroxy-4-methylpentanoic acid: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in 4-Hydroxy-4-methylpentanoic acid: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in 4-Hydroxy-4-methylpentanoic acid: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in 4-Hydroxy-4-methylpentanoic acid: 1.008 x 12 = 12.096

Number of Oxygen atoms in 4-Hydroxy-4-methylpentanoic acid: 3
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in 4-Hydroxy-4-methylpentanoic acid: 15.9994 x 3 = 47.9982

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

Molecular weight of 4-Hydroxy-4-methylpentanoic acid: 72.0642 (Carbon) + 12.096 (Hydrogen) + 47.9982 (Oxygen) = 132.1584

So the molecular weight of 4-Hydroxy-4-methylpentanoic acid is 132.1584.
