# Hydroquinone [C6H4(OH)2] Molecular Weight Calculation

The molecular weight of Hydroquinone [C6H4(OH)2] is 110.111.

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: Hydroquinone [C6H4(OH)2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Hydroquinone molecule.
From the chemical formula, you will know different atoms and their number in a Hydroquinone molecule. Chemical formula of Hydroquinone is C6H6O2. From the chemical formula of Hydroquinone, you can find that one molecule of Hydroquinone has six Carbon (C) atoms, six 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 Hydroquinone molecule by multiplying its atomic weight by its number.

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

Number of Hydrogen atoms in Hydroquinone: 6
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Hydroquinone: 1.008 x 6 = 6.048

Number of Oxygen atoms in Hydroquinone: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Hydroquinone: 15.9994 x 2 = 31.9988

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

Molecular weight of Hydroquinone: 72.0642 (Carbon) + 6.048 (Hydrogen) + 31.9988 (Oxygen) = 110.111

So the molecular weight of Hydroquinone is 110.111.
