CALCULATION PROCEDURE: 15-Crown-5 [C10H20O5] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a 15-Crown-5 molecule.
You will know different atoms and their number in a 15-Crown-5 molecule from the chemical formula. The chemical formula of 15-Crown-5 is C10H20O5. From the chemical formula, you can find that one molecule of 15-Crown-5 consists of ten Carbon (C) atoms, twenty Hydrogen (H) atoms, and five 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 in a 15-Crown-5 molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in 15-Crown-5: 10
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in 15-Crown-5: 12.0107 x 10 = 120.107
Number of Hydrogen atoms in 15-Crown-5: 20
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in 15-Crown-5: 1.008 x 20 = 20.16
Number of Oxygen atoms in 15-Crown-5: 5
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in 15-Crown-5: 15.9994 x 5 = 79.997
Step 4: Calculate the molecular weight of 15-Crown-5 by adding up the total weight of all atoms.
Molecular weight of 15-Crown-5: 120.107 (Carbon) + 20.16 (Hydrogen) + 79.997 (Oxygen) = 220.264
So the molecular weight of 15-Crown-5 is 220.264.
