# Methyl Benzoate [C6H5COOCH3] Molecular Weight Calculation

The molecular weight of Methyl benzoate [C6H5COOCH3] is 136.1484. Methyl benzoate [C6H5COOCH3] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Methyl benzoate is 136.1484 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Methyl benzoate [C6H5COOCH3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Methyl benzoate molecule.
You will know different atoms and their number in a Methyl benzoate molecule from the chemical formula. The chemical formula of Methyl benzoate is C8H8O2. From the chemical formula, you can find that one molecule of Methyl benzoate has eight Carbon (C) atoms, eight Hydrogen (H) atoms, and two Oxygen (O) atoms.

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 Methyl benzoate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Methyl benzoate: 8
Atomic weight of Carbon (C)
: 12.0107
Total weight of Carbon atoms in Methyl benzoate: 12.0107 x 8 = 96.0856

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

Number of Oxygen atoms in Methyl benzoate: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Methyl benzoate: 15.9994 x 2 = 31.9988

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

Molecular weight of Methyl benzoate: 96.0856 (Carbon) + 8.064 (Hydrogen) + 31.9988 (Oxygen) = 136.1484

So the molecular weight of Methyl benzoate is 136.1484.
