The molecular weight of Maltose (C12H22O11) is 342.2978.
Maltose (C12H22O11) is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Maltose is 342.2978 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Maltose (C12H22O11) Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Maltose molecule.
You will know different atoms and their number in a Maltose molecule from the chemical formula. The chemical formula of Maltose is C12H22O11. From the chemical formula, you can find that one molecule of Maltose has twelve Carbon (C) atoms, twenty-two Hydrogen (H) atoms and eleven 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 Maltose molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Maltose: 12
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Maltose: 12.0107 x 12 = 144.1284
Number of Hydrogen atoms in Maltose: 22
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Maltose: 1.008 x 22 = 22.176
Number of Oxygen atoms in Maltose: 11
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Maltose: 15.9994 x 11 = 175.9934
Step 4: Calculate the molecular weight of Maltose by adding up the total weight of all atoms.
Molecular weight of Maltose: 144.1284 (Carbon) + 22.176 (Hydrogen) + 175.9934 (Oxygen) = 342.2978
So the molecular weight of Maltose is 342.2978.
