The molecular weight of Cyclopropane [(CH₂)₃] is 42.0801.

Cyclopropane [(CH₂)₃] is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Cyclopropane is 42.0801 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Cyclopropane  [(CH₂)₃] Molecular Weight Calculation

Step 1: Find the chemical formula and determine constituent atoms and their number in a Cyclopropane molecule.
You will know different atoms and their number in a Cyclopropane molecule from the chemical formula. The chemical formula of Cyclopropane is C₂H₆. The chemical formula shows that one Cyclopropane molecule consists of nineteen Carbon (C) atoms and forty Hydrogen (H) atoms.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Hydrogen (H): 1.008 (Ref: Lanl-1)

Step 3: Calculate the total weight of each atom in a Cyclopropane molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Cyclopropane: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Cyclopropane: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Cyclopropane: 6
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Cyclopropane: 1.008 x 6 = 6.048

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

Molecular weight of Cyclopropane: 36.0321 (Carbon) + 6.048 (Hydrogen) = 42.0801

So the molecular weight of Cyclopropane is 42.0801.
