Final answer:
In the synthesis of a complex carbohydrate from nine monosaccharide molecules, eight water molecules are removed. Initially, there would be 108 hydrogen atoms, but after the removal of 16 hydrogen atoms with the water, 92 hydrogen atoms remain in the final polymer.
Step-by-step explanation:
When assembling nine molecules of a monosaccharide with the formula C₆H₁₂O₆ to create a complex carbohydrate, one must account for the water molecules that are removed during the formation of each glycosidic bond. For each bond formed, one molecule of water (H₂O) is removed. Since we are combining nine monosaccharides, eight glycosidic bonds will be formed (since the first monosaccharide does not require bonding with another), resulting in the removal of eight water molecules.
Each monosaccharide has 12 hydrogen atoms, so nine of them would initially contain 108 hydrogen atoms (9 x 12). However, because each water molecule removed contains two hydrogen atoms and eight water molecules are removed, 16 hydrogen atoms will be lost (8 x 2). Thus, in the final complex carbohydrate polymer, there will be 92 hydrogen atoms (108 initial hydrogen atoms - 16 hydrogen atoms lost).
