sec-Butyl acetate [CH3CO2CH(CH3)C2H5] Molecular Weight Calculation

The molecular weight of sec-Butyl acetate [CH3CO2CH(CH3)C2H5] is 116.159.

sec-Butyl acetate [CH3CO2CH(CH3)C2H5] Molecular Weight CalculationTo 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: sec-Butyl acetate [CH3CO2CH(CH3)C2H5] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a sec-Butyl acetate molecule.
From the chemical formula, you will know different atoms and their number in a sec-Butyl acetate molecule. Chemical formula of sec-Butyl acetate is C6H12O2. From the chemical formula of sec-Butyl acetate, you can find that one molecule of sec-Butyl acetate has six Carbon (C) atoms, twelve 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 sec-Butyl acetate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in sec-Butyl acetate: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in sec-Butyl acetate: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in sec-Butyl acetate: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in sec-Butyl acetate: 1.008 x 12 = 12.096

Number of Oxygen atoms in sec-Butyl acetate: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in sec-Butyl acetate: 15.9994 x 2 = 31.9994

Step 4: Calculate the molecular weight of sec-Butyl acetate by adding up the total weight of all atoms.

Molecular weight of sec-Butyl acetate: 72.0642 (Carbon) + 12.096 (Hydrogen) + 31.9994 (Oxygen) = 116.159

So the molecular weight of sec-Butyl acetate is 116.159.
