Question

Suppose a piece of silver jewelry contains 7.78×1022 atomsatoms of silver (AgAg).

There are several common counting units:
1 dozen
12,
1 score = 20,
1 ream = = 500, and
1 gross
= 144.
The mole (mol) is a counting unit used by chemists, much
like the dozen is a counting unit used by bakers:
1 mol = 6.022 × 1023
