The molecular weight of Sophorose (C_{12}H_{22}O_{11}) 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: Sophorose (C**_{12}H_{22}O_{11}) Molecular Weight Calculation

_{12}H

_{22}O

_{11}) Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Sophorose molecule.**From the chemical formula, you will know different atoms and their number in a Sophorose molecule. Chemical formula of Sophorose is C

_{12}H

_{22}O

_{11}. From the chemical formula of Sophorose, you can find that one molecule of Sophorose 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 Sophorose molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in Sophorose: 12

Atomic weight of Carbon: 12.0107

Total weight of Carbon atoms in Sophorose: 12.0107 x 12 = 144.1284

Number of Hydrogen atoms in Sophorose: 22

Atomic weight of Hydrogen: 1.008

Total weight of Hydrogen atoms in Sophorose: 1.008 x 22 = 22.176

Number of Oxygen atoms in Sophorose: 11

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Sophorose: 15.9994 x 11 = 175.9934

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

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

So the molecular weight of Sophorose is 342.2978.
