Breaking bonds is hydrolysis. is dehydration synthesis. stores energy. is endergonic.

How is Avogadro's number related to the numbers on the periodic table? The masses are all divisible by Avogadro's number which gives you the weight of one mole. The atomic mass listed is the mass of Avogadro's number's worth of atoms. The periodic table tells you the mass of one atom. From that,and Avogadro's number you know the number of moles. The periodic table only gives us atomic numbers not atomic mass. The mass listed is Avogadro's number.
