_{2})

_{2}CHCH

_{3}] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in an Ethylidene diacetate molecule.**You will know different atoms and their number in an Ethylidene diacetate molecule from the chemical formula. The chemical formula of Ethylidene diacetate is C

_{6}H

_{10}O

_{4}. From the chemical formula of Ethylidene diacetate, you can find that one molecule of Ethylidene diacetate has six Carbon (C) atoms, ten Hydrogen (H) atoms, and four 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 an Ethylidene diacetate molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in Ethylidene diacetate: 6

Atomic weight of Carbon: 12.0107

Total weight of Carbon atoms in Ethylidene diacetate: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Ethylidene diacetate: 10

Atomic weight of Hydrogen: 1.008

Total weight of Hydrogen atoms in Ethylidene diacetate: 1.008 x 10 = 10.08

Number of Oxygen atoms in Ethylidene diacetate: 4

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Ethylidene diacetate: 15.9994 x 4 = 63.9976

**Step 4: Calculate the molecular weight of Ethylidene diacetate by adding up the total weight of all atoms. **

Molecular weight of Ethylidene diacetate: 72.0642 (Carbon) + 10.08 (Hydrogen) + 63.9976 (Oxygen) = 146.1418

So the molecular weight of Ethylidene diacetate is 146.1418.
