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:

$\frac{327}{1000} = 0 , 327 g$

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

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