# Cycloprop-2-ene Carboxylic Acid (C4H4O2) Molecular Weight Calculation

The molecular weight of Cycloprop-2-ene carboxylic acid (C4H4O2) is 84.0736.

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: Cycloprop-2-ene carboxylic acid (C4H4O2) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Cycloprop-2-ene carboxylic acid molecule.
From the chemical formula, you will know different atoms and their number in a Cycloprop-2-ene carboxylic acid molecule. Chemical formula of Cycloprop-2-ene carboxylic acid is C2H4O2. From the chemical formula of Cycloprop-2-ene carboxylic acid, you can find that one molecule of Cycloprop-2-ene carboxylic acid has four Carbon (C) atoms, four 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 Cycloprop-2-ene carboxylic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Cycloprop-2-ene carboxylic acid: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Cycloprop-2-ene carboxylic acid: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Cycloprop-2-ene carboxylic acid: 4
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Cycloprop-2-ene carboxylic acid: 1.008 x 4 = 4.032

Number of Oxygen atoms in Cycloprop-2-ene carboxylic acid: 2
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Cycloprop-2-ene carboxylic acid: 15.9994 x 2 = 31.9988

Step 4: Calculate the molecular weight of Cycloprop-2-ene carboxylic acid by adding up the total weight of all atoms.

Molecular weight of Cycloprop-2-ene carboxylic acid: 48.0428 (Carbon) + 4.032 (Hydrogen) + 31.9988 (Oxygen) = 84.0736

So the molecular weight of Cycloprop-2-ene carboxylic acid is 84.0736.
