Answer:

Number of silver atoms

=

0.0134

⋅

Avogadro's number

Explanation:

Silver has a molar mass of  

107.87

g

⋅

What does this mean? It means that if I have such a mass of silver, there are Avogadro's number,  

N

A

=

6.022

,  

individual silver atoms.

So all I have to do is divide the mass by the molar mass, and multiply this number (a molar quantity!) by Avogadro's number.  

So, moles of silver  

=

1.45
