I'll walk you through this

Explanation:

First you will want to get a common unit (e.g. grams); hence, you will want to convert 327mg into grams:

#327/1000=0,327g#

Knowing that one silver atom weighs #1.79×10^-22# grams, you will have to merely divide 0,327g by #1.79×10^-22#g. I.e.:

#(0,327g)/(1.79×10^-22g)=1,83×10^21# atoms of silver
