The molecular weight of Tagatose (C6H12O6) is 180.1566.
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: Tagatose (C6H12O6) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Tagatose molecule.
From the chemical formula, you will know different atoms and their number in a Tagatose molecule. Chemical formula of Tagatose is C6H12O6. From the chemical formula of Tagatose, you can find that one molecule of Tagatose have six Carbon (C) atoms, twelve Hydrogen (H) atoms and six 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 Tagatose molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Tagatose: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Tagatose: 12.0107 x 6 = 72.0642
Number of Hydrogen atoms in Tagatose: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Tagatose: 1.008 x 12 = 12.096
Number of Oxygen atoms in Tagatose: 6
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Tagatose: 15.9994 x 6 = 95.9964
Step 4: Calculate the molecular weight of Tagatose by adding up the total weight of all atoms.
Molecular weight of Tagatose: 72.0642 (Carbon) + 12.096 (Hydrogen) + 95.9964 (Oxygen) = 180.1566
So the molecular weight of Tagatose is 180.1566.
