# Diacetone Alcohol [(CH3)2C(OH)CH2COCH3] Molecular Weight Calculation

The molecular weight of Diacetone Alcohol [(CH3)2C(OH)CH2COCH3] is 116.159.

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: Diacetone Alcohol [(CH3)2C(OH)CH2COCH3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Diacetone Alcohol molecule.
From the chemical formula, you will know different atoms and their number in a Diacetone Alcohol molecule. Chemical formula of Diacetone Alcohol is C6H12O2. From the chemical formula of Diacetone Alcohol, you can find that one molecule of Diacetone Alcohol has six Carbon (C) atoms, twelve Hydrogen (H) atoms and two 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 Diacetone Alcohol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Diacetone Alcohol: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Diacetone Alcohol: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Diacetone Alcohol: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Diacetone Alcohol: 1.008 x 12 = 12.096

Number of Oxygen atoms in Diacetone Alcohol: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Diacetone Alcohol: 15.9994 x 2 = 31.9994

Step 4: Calculate the molecular weight of Diacetone Alcohol by adding up the total weight of all atoms.

Molecular weight of Diacetone Alcohol: 72.0642 (Carbon) + 12.096 (Hydrogen) + 31.9994 (Oxygen) = 116.159

So the molecular weight of Diacetone Alcohol is 116.159.
