The molecular weight of Pentene (C5H10) is 70.1335.
Pentene (C5H10) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Pentene is 70.1335 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Pentene [C5H10] Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in a Pentene molecule.
You will know different atoms and their number in a Pentene molecule from the chemical formula. The chemical formula of Pentene is C5H10. The chemical formula shows that one Pentene molecule consists of five Carbon (C) atoms and ten 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 Pentene molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Pentene: 5
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Pentene: 12.0107 x 5 = 60.0535
Number of Hydrogen atoms in Pentene: 10
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Pentene: 1.008 x 10 = 10.08
Step 4: Calculate the molecular weight of Pentene by adding up the total weight of all atoms.
Molecular weight of Pentene: 60.0535 (Carbon) + 10.08 (Hydrogen) = 70.1335
So the molecular weight of Pentene is 70.1335.
