Answer:
623 monomers
Explanation:
In a dehydration synthesis reaction, one water molecule is removed for every bond that is created between 2 monomers.
Linking 3 monomers together would remove 2 water molecules.
Following this pattern, the number of water molecules removed will always be one less than the number of monomers that were joined together.
So, if 622 water molecules were removed, then 623 monomers were joined together.
The answer is 623 monomers.
