The molecular weight of Turanose (C₁₂H₂₂O₁₁) is 342.2978.

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: Turanose (C₁₂H₂₂O₁₁) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Turanose molecule.
From the chemical formula, you will know different atoms and their number in a Turanose molecule. Chemical formula of Turanose is C₁₂H₂₂O₁₁. From the chemical formula of Turanose, you can find that one molecule of Turanose 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 Turanose molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Turanose: 12
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Turanose: 12.0107 x 12 = 144.1284

Number of Hydrogen atoms in Turanose: 22
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Turanose: 1.008 x 22 = 22.176

Number of Oxygen atoms in Turanose: 11
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Turanose: 15.9994 x 11 = 175.9934

Step 4: Calculate the molecular weight of Turanose by adding up the total weight of all atoms.

Molecular weight of Turanose: 144.1284 (Carbon) + 22.176 (Hydrogen) + 175.9934 (Oxygen) = 342.2978

So the molecular weight of Turanose is 342.2978.
