1,3-Butanediol [CH3CH(OH)CH2CH2OH] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of 1,3-Butanediol is 90.1216 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: 1,3-Butanediol [CH3CH(OH)CH2CH2OH] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a 1,3-Butanediol molecule.
You will know different atoms and their number in a 1,3-Butanediol molecule from the chemical formula. The chemical formula of 1,3-Butanediol is C4H10O2. From the chemical formula, you can find that one molecule of 1,3-Butanediol has four Carbon (C) atoms, ten Hydrogen (H) atoms, and two Oxygen (O) atoms.
Step 2: Find out atomic weights of each atom (from the periodic table).
Step 3: Calculate the total weight of each atom in a 1,3-Butanediol molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in 1,3-Butanediol: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in 1,3-Butanediol: 12.0107 x 4 = 48.0428
Number of Hydrogen atoms in 1,3-Butanediol: 10
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in 1,3-Butanediol: 1.008 x 10 = 10.08
Number of Oxygen atoms in 1,3-Butanediol: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in 1,3-Butanediol: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of 1,3-Butanediol by adding up the total weight of all atoms.
Molecular weight of 1,3-Butanediol: 48.0428 (Carbon) + 10.08 (Hydrogen) + 31.9988 (Oxygen) = 90.1216
So the molecular weight of 1,3-Butanediol is 90.1216.
