The molecular weight of Glucose (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: Glucose (C6H12O6) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Glucose molecule.
From the chemical formula, you will know different atoms and their number in a Glucose molecule. Chemical formula of Glucose is C6H12O6. From the chemical formula of Glucose, you can find that one molecule of Glucose has 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).
Step 3: Calculate the total weight of each atom present in a Glucose molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Glucose: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Glucose: 12.0107 x 6 = 72.0642
Number of Hydrogen atoms in Glucose: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Glucose: 1.008 x 12 = 12.096
Number of Oxygen atoms in Glucose: 6
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Glucose: 15.9994 x 6 = 95.9964
Step 4: Calculate the molecular weight of Glucose by adding up the total weight of all atoms.
Molecular weight of Glucose: 72.0642 (Carbon) + 12.096 (Hydrogen) + 95.9964 (Oxygen) = 180.1566
So the molecular weight of Glucose is 180.1566.
