Explanation:
Detailed explanation-1: -According to the molecular formula of 10 glucose molecules ( C 60 H 120 O 60 ), there must be 60 carbon, 120 hydrogen, and 60 oxygen atoms. However, in dehydration reaction of 10 glucose molecules, 9 water molecules are formed, consisting of 18 hydrogen atoms and 9 oxygen atoms.
Detailed explanation-2: -Following the above pattern, if 500 glucose molecules were linked, 499 molecules of H2O would be produced (i.e., 499 bonds formed).
