Methyl Pyruvate (CH3C(O)CO2CH3) Molecular Weight Calculation

The molecular weight of Methyl pyruvate (CH3C(O)CO2CH3) is 102.089.

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: Methyl pyruvate (CH3C(O)CO2CH3) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Methyl pyruvate molecule.
From the chemical formula, you will know different atoms and their number in a Methyl pyruvate molecule. Chemical formula of Methyl pyruvate is C4H6O3. From the chemical formula of Methyl pyruvate, you can find that one molecule of Methyl pyruvate has four Carbon (C) atoms, six Hydrogen (H) atoms and three 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 Methyl pyruvate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Methyl pyruvate: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Methyl pyruvate: 12.0107 x 4 = 48.0428

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

Number of Oxygen atoms in Methyl pyruvate: 3
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Methyl pyruvate: 15.9994 x 3 = 47.9982

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

Molecular weight of Methyl pyruvate: 48.0428 (Carbon) + 6.048 (Hydrogen) + 47.9982 (Oxygen) = 102.089

So the molecular weight of Methyl pyruvate is 102.089.
