Answer 2

★★★Hey there★★★

Mole is just a measuring term like dozen or something else. Just like 1 dozen have 12 units, in the same way 1 mole have 6.022*10²³ units.

Well, this amount is equal to 12 grams of C-12 isotope of carbon and approximately equal to 1 gram of hydrogen atom.

Well the concept is too easy, an atom have an atomic mass of x amu. Then x grams of the same element will have 6.022*10²³ or 1 mole atoms.
