Question #330ff

Answer 1

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
