# Galactitol [C6H14O6] Molecular Weight Calculation

The molecular weight of Galactitol [C6H14O6] is 182.1726. 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: Galactitol [C6H14O6] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Galactitol molecule.
From the chemical formula, you will know different atoms and their number in a Galactitol molecule. Chemical formula of Galactitol is C6H14O6. From the chemical formula of Galactitol, you can find that one molecule of Galactitol has six Carbon (C) atoms, fourteen Hydrogen (H) atoms and six 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
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 Galactitol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Galactitol: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Galactitol: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Galactitol: 14
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Galactitol: 1.008 x 14 = 14.112

Number of Oxygen atoms in Galactitol: 6
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Galactitol: 15.9994 x 6 = 95.9964

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

Molecular weight of Galactitol: 72.0642 (Carbon) + 14.112 (Hydrogen) + 95.9964 (Oxygen) = 182.1726

So the molecular weight of Galactitol is 182.1726.
