The molecular weight of Propane (C3H8) is 44.0961.
Propane (C3H8) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Propane is 44.0961 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Propane [C3H8] Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in a Propane molecule.
You will know different atoms and their number in a Propane molecule from the chemical formula. The chemical formula of Propane is C3H8. The chemical formula shows that one Propane molecule consists of three Carbon (C) atoms and eight Hydrogen (H) atoms.
Step 2: Find out the atomic weights of each atom (from the periodic table).
Step 3: Calculate the total weight of each atom in a Propane molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Propane: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Propane: 12.0107 x 3 = 36.0321
Number of Hydrogen atoms in Propane: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Propane: 1.008 x 8 = 8.064
Step 4: Calculate the molecular weight of Propane by adding up the total weight of all atoms.
Molecular weight of Propane: 36.0321 (Carbon) + 8.064 (Hydrogen) = 44.0961
So the molecular weight of Propane is 44.0961.
