Trimethyl orthobenzoate [C₆H₅C(OCH₃)₃] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Trimethyl orthobenzoate is 182.2172 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Trimethyl orthobenzoate [C₆H₅C(OCH₃)₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Trimethyl orthobenzoate molecule.
You will know different atoms and their number in a Trimethyl orthobenzoate molecule from the chemical formula. The chemical formula of Trimethyl orthobenzoate is C₁₀H₁₄O₃. From the chemical formula, you can find that one molecule of Trimethyl orthobenzoate has ten Carbon (C) atoms, fourteen Hydrogen (H) atoms, and three 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 Trimethyl orthobenzoate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Trimethyl orthobenzoate: 10
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Trimethyl orthobenzoate: 12.0107 x 10 = 120.107

Number of Hydrogen atoms in Trimethyl orthobenzoate: 14
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Trimethyl orthobenzoate: 1.008 x 14 = 14.112

Number of Oxygen atoms in Trimethyl orthobenzoate: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Trimethyl orthobenzoate: 15.9994 x 3 = 47.9982

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

Molecular weight of Trimethyl orthobenzoate: 120.107 (Carbon) + 14.112 (Hydrogen) + 47.9982 (Oxygen) = 182.2172

So the molecular weight of Trimethyl orthobenzoate is 182.2172.
