What would be the molecular formula of a disaccharide made from linking 2 monomers of glucose?

342.297 g/mol

Explanation:

The molecular weight of a glucose molecule is 180.156g/mol.

The molecular weight of a disaccharide will be a bit less than the sum of two glucose monomers because, in the formation of the glycosidic bond, a water molecule is expunged because it is a dehydration synthesis reaction. A water molecule's molecular weight is 18.015g/mol.

Therefore the molecular weight of a disaccharide will be approximate;

(180.156 + 180.156) - 18.015 = 360.312‬ - 18.015 = 342.297 g/mol
