1-Methoxypropane (Methyl propyl ether) [C4H10O] Molecular Weight Calculation

The molecular weight of 1-Methoxypropane [C4H10O] is 74.1222.

1-Methoxypropane [C4H10O] Molecular Weight CalculationTo calculate molecular weight of any compound, the first step is to know the constituent atoms and their number in that particular compound. Then calculate the total weight of each atom by multiplying its atomic weight by its number. The sum of total weight of all constituent atoms will be the molecular weight of the compound. Note that the value of atomic weight may differ slightly from different sources.

CALCULATION PROCEDURE: 1-Methoxypropane [C4H10O] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a 1-Methoxypropane molecule.
From the chemical formula, you will know different atoms and their number in a 1-Methoxypropane molecule. Chemical formula of 1-Methoxypropane is C4H10O. From the chemical formula of 1-Methoxypropane, you can find that one molecule of 1-Methoxypropane has four Carbon (C) atoms, ten Hydrogen (H) atoms and one Oxygen (O) atom.

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 1-Methoxypropane molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in 1-Methoxypropane: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in 1-Methoxypropane: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in 1-Methoxypropane: 10
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in 1-Methoxypropane: 1.008 x 10 = 10.08

Number of Oxygen atoms in 1-Methoxypropane: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in 1-Methoxypropane: 15.9994 x 1 = 15.9994

Step 4: Calculate the molecular weight of 1-Methoxypropane by adding up the total weight of all atoms.

Molecular weight of 1-Methoxypropane: 48.0428 (Carbon) + 10.08 (Hydrogen) + 15.9994 (Oxygen) = 74.1222

So the molecular weight of 1-Methoxypropane is 74.1222.
