_{10}H

_{16}O

_{4}] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a 2-Decenedioic acid molecule.**You will know different atoms and their number in a 2-Decenedioic acid molecule from the chemical formula. The chemical formula of 2-Decenedioic acid is C

_{10}H

_{16}O

_{4}. From the chemical formula, you can find that one molecule of 2-Decenedioic acid consists of ten Carbon (C) atoms, sixteen 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 a 2-Decenedioic acid molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in 2-Decenedioic acid: 10

Atomic weight of Carbon: 12.0107

Total weight of Carbon atoms in 2-Decenedioic acid: 12.0107 x 10 = 120.107

Number of Hydrogen atoms in 2-Decenedioic acid: 16

Atomic weight of Hydrogen: 1.008

Total weight of Hydrogen atoms in 2-Decenedioic acid: 1.008 x 16 = 16.128

Number of Oxygen atoms in 2-Decenedioic acid: 4

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in 2-Decenedioic acid: 15.9994 x 4 = 63.9976

**Step 4: Calculate the molecular weight of 2-Decenedioic acid by adding up the total weight of all atoms. **

Molecular weight of 2-Decenedioic acid: 120.107 (Carbon) + 16.128 (Hydrogen) + 63.9976 (Oxygen) = 200.2326

So the molecular weight of 2-Decenedioic acid is 200.2326.
