15-Crown-5 [C10H20O5] Molecular Weight Calculation15-Crown-5 [C10H20O5] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of 15-Crown-5 [C10H20O5] is 220.264 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Carbon, Hydrogen, Nitrogen and Oxygen. 

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.
From the chemical formula, you will know different atoms and their number in a 15-Crown-5 molecule. Chemical formula of 15-Crown-5 is C10H20O5. From the chemical formula of 15-Crown-5, you can find that one molecule of 15-Crown-5 has 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 present 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.
