The molecular weight of Benzyl alcohol [C₆H₅CH₂OH] is 108.1383.

Benzyl alcohol [C₆H₅CH₂OH] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Benzyl alcohol is 108.1383 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Benzyl alcohol [C₆H₅CH₂OH] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Benzyl alcohol molecule.
You will know different atoms and their number in a Benzyl alcohol molecule from the chemical formula. The chemical formula of Benzyl alcohol is C₇H₈O₁. From the chemical formula, you can find that one molecule of Benzyl alcohol has seven Carbon (C) atoms, eight Hydrogen (H) atoms, and one Oxygen (O) atom.

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 present in a Benzyl alcohol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Benzyl alcohol: 7
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Benzyl alcohol: 12.0107 x 7 = 84.0749

Number of Hydrogen atoms in Benzyl alcohol: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Benzyl alcohol: 1.008 x 8 = 8.064

Number of Oxygen atoms in Benzyl alcohol: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Benzyl alcohol: 15.9994 x 1 = 15.9994

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

Molecular weight of Benzyl alcohol: 84.0749 (Carbon) + 8.064 (Hydrogen) + 15.9994 (Oxygen) = 108.1383

So the molecular weight of Benzyl alcohol is 108.1383.
