# 2-Hydroxyisocaproic Acid [(CH3)2CHCH2CH(OH)CO2H] Molecular Weight Calculation

The molecular weight of 2-Hydroxyisocaproic acid [(CH3)2CHCH2CH(OH)CO2H] is 132.1584. 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: 2-Hydroxyisocaproic acid [(CH3)2CHCH2CH(OH)CO2H] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a 2-Hydroxyisocaproic acid molecule.
From the chemical formula, you will know different atoms and their number in a 2-Hydroxyisocaproic acid molecule. Chemical formula of 2-Hydroxyisocaproic acid is C6H12O3. From the chemical formula of 2-Hydroxyisocaproic acid, you can find that one molecule of 2-Hydroxyisocaproic 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 2-Hydroxyisocaproic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in 2-Hydroxyisocaproic acid: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in 2-Hydroxyisocaproic acid: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in 2-Hydroxyisocaproic acid: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in 2-Hydroxyisocaproic acid: 1.008 x 12 = 12.096

Number of Oxygen atoms in 2-Hydroxyisocaproic acid: 3
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in 2-Hydroxyisocaproic acid: 15.9994 x 3 = 47.9982

Step 4: Calculate the molecular weight of 2-Hydroxyisocaproic acid by adding up the total weight of all atoms.

Molecular weight of 2-Hydroxyisocaproic acid: 72.0642 (Carbon) + 12.096 (Hydrogen) + 47.9982 (Oxygen) = 132.1584

So the molecular weight of 2-Hydroxyisocaproic acid is 132.1584.
