Deoxyribose (C5H10O4) Molecular Weight Calculation

The molecular weight of Deoxyribose (C5H10O4) is 134.1311.

Deoxyribose (Sugar) 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: DEOXYRIBOSE (C5H10O4) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Deoxyribose molecule.
From the chemical formula, you will know different atoms and their number in a Deoxyribose molecule. Chemical formula of Deoxyribose is C5H10O4. From the chemical formula of Deoxyribose, you can find that one molecule of Deoxyribose has five 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 present in a Deoxyribose molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Deoxyribose: 5
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Deoxyribose: 12.0107 x 5 = 60.0535

Number of Hydrogen atoms in Deoxyribose: 10
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Deoxyribose: 1.008 x 10 = 10.080

Number of Oxygen atoms in Deoxyribose: 4
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Deoxyribose: 15.9994 x 5 = 63.9976

Step 4: Calculate the molecular weight of Deoxyribose by adding up the total weight of all atoms.

Molecular weight of Deoxyribose: 60.0535 (Carbon) + 10.080 (Hydrogen) + 63.9976 (Oxygen) = 134.1311

So the molecular weight of Deoxyribose is 134.1311.
