Developement of avogadro's number/mole concept?

Answer 1

All I know is that he made the avogadro's number.

6.022 x 10^23 atoms

I have no idea how he calculated that. That is suppose to be the number of atoms in 1 mole of an element.

Answer 2

Are you looking for someone to derive this number? Look in your texts. Most chemistry and physics texts have it.
