The molecular weight of Tetrahydrofuran [(CH2)4O] is 72.1062.
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: Tetrahydrofuran [(CH2)4O] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Tetrahydrofuran molecule.
From the chemical formula, you will know different atoms and their number in a Tetrahydrofuran molecule. Chemical formula of Tetrahydrofuran is C4H8O. From the chemical formula of Tetrahydrofuran, you can find that one molecule of Tetrahydrofuran has four Carbon (C) atoms, eight Hydrogen (H) atoms and one Oxygen (O) atom.
Step 2: Find out atomic weights of each atom (from periodic table).
Step 3: Calculate the total weight of each atom present in a Tetrahydrofuran molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Tetrahydrofuran: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Tetrahydrofuran: 12.0107 x 4 = 48.0428
Number of Hydrogen atoms in Tetrahydrofuran: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Tetrahydrofuran: 1.008 x 8 = 8.064
Number of Oxygen atoms in Tetrahydrofuran: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Tetrahydrofuran: 15.9994 x 1 = 15.9994
Step 4: Calculate the molecular weight of Tetrahydrofuran by adding up the total weight of all atoms.
Molecular weight of Tetrahydrofuran: 48.0428 (Carbon) + 8.064 (Hydrogen) + 15.9994 (Oxygen) = 72.1062
So the molecular weight of Tetrahydrofuran is 72.1062.
