The molecular weight of Lyxose (C5H10O5) is 150.1305.
To 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: Lyxose (C5H10O5) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Lyxose molecule.
From the chemical formula, you will know different atoms and their number in a Lyxose molecule. Chemical formula of Lyxose is C5H10O5. From the chemical formula of Lyxose, you can find that one molecule of Lyxose have five Carbon (C) atoms, ten 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 Lyxose molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Lyxose: 5
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Lyxose: 12.0107 x 5 = 60.0535
Number of Hydrogen atoms in Lyxose: 10
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Lyxose: 1.008 x 10 = 10.080
Number of Oxygen atoms in Lyxose: 5
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Lyxose: 15.9994 x 5 = 79.997
Step 4: Calculate the molecular weight of Lyxose by adding up the total weight of all atoms.
Molecular weight of Lyxose: 60.0535 (Carbon) + 10.080 (Hydrogen) + 79.997 (Oxygen) = 150.1305
So the molecular weight of Lyxose is 150.1305.
