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