The molecular weight of Cyclobutanol [C₄H₇OH] 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: Cyclobutanol [C₄H₇OH] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Cyclobutanol molecule.
From the chemical formula, you will know different atoms and their number in a Cyclobutanol molecule. Chemical formula of Cyclobutanol is C₄H₈O. From the chemical formula of Cyclobutanol, you can find that one molecule of Cyclobutanol 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).

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 Cyclobutanol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Cyclobutanol: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Cyclobutanol: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Cyclobutanol: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Cyclobutanol: 1.008 x 8 = 8.064

Number of Oxygen atoms in Cyclobutanol: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Cyclobutanol: 15.9994 x 1 = 15.9994

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

Molecular weight of Cyclobutanol: 48.0428 (Carbon) + 8.064 (Hydrogen) + 15.9994 (Oxygen) = 72.1062

So the molecular weight of Cyclobutanol is 72.1062.
