~~53.bar 6*10^21

Explanation:

In your question, you say "how many." This is the same as saying "divided into." Since you want to know how many "dozens", which is 12, go into 6.44*10^22, we simply do this:
(6.44*10^22)/12

=(3.22*10^22)/6

=(32.2*10^21)/6

=5.36666666666666666667*10^21

=5.3bar 6*10^21, which is how many dozens of atoms there are in that piece of silver jewellery.

I hope that helped!
