Verified step by step guidance

Understand that dehydration synthesis involves the removal of a water molecule (H2O) for each glycosidic bond formed between glucose molecules.

Calculate the number of water molecules removed: For 10 glucose molecules linked together, 9 glycosidic bonds are formed, thus 9 water molecules are removed.

Determine the molecular formula of the initial 10 glucose molecules: (C6H12O6)10, which is C60H120O60.

Subtract the atoms of the 9 water molecules removed: Each water molecule is H2O, so 9 H2O molecules contribute 18 hydrogen atoms and 9 oxygen atoms, resulting in a total removal of H18O9.

Adjust the molecular formula by subtracting the atoms removed: C60H120O60 - H18O9 = C60H102O51, which is the molecular formula for the oligosaccharide.
