If nine molecules of a monosaccharide with the formula c6h12o6 are assembled to produce a complex carbohydrate, how much atoms of hydrogen will be in the final polymer

There are 8 bond are formed and 8 molecules of H2O are released.

there are 2 hydrogen in one H2O it means 8 x 2 = 16 hydrogen

and,

nine molecules of a monosaccharide with the formula c6h12o6

so there is 9 x 12 = 108 hydrogen atoms

Atoms of hydrogen will be in the final polymer = 108 - 16 = 92

So, 92 hydrogen will be in final polymer.
