The formula weight of lactose, C12H22O11, is approximately 342.3 g/mol.
A disaccharide is composed of two monosaccharide's that are linked by a glycoside bond. Its chemical formula is C12H22O11. Examples of disaccharides are sucrose, lactose and maltose.
To draw the structural formula for lactose, start with a glucose molecule. Attach a galactose molecule to the glucose molecule through a beta-1,4 glycosidic bond. This forms the disaccharide lactose.

C12H22O11 This is the chemical formula for the disaccharides sucrose, lactose, and maltose.
There are 9 oxygen atoms in the chemical formula for lactose, which is C12H22O11.
Lactose (C12H22O11), which is known to some as milk sugar, is a disaccharide. You can view its chemical structure by using the link which is provided to surf over to the Wikipedia article on lactose.
The empirical formula for maltose is C12H22O11, for sucrose it is C12H22O11, and for lactose it is C12H22O11. This means that all three sugars have the same empirical formula.
The chemical fomula for galactose is C6 H12 O6
The molecular formula C12 H22 O11 is for DISCCHARIDES (sugars) -three different sugars - with different molecular structures, BUT ONLY ONE: molecular formula : 1. Lactose 2. Sucrose 3. Maltose The three sugars all have the same formula , but the structure represents the combination of two sugars - that is they are Discaccharide Type Sugars (dis,as two). to identify the formula -to a particular sugar we must know how it is structured as : LACTOSE= GLUCOSE + GALACTOSE FRUCTOSE = GLUCOSE + FRUCTOSE MALTOSE = GLUCOSE + GLUCOSE Sugar is Sugar by formula but not by structure.
