What is the mass of 6874x 10^23 atoms Ag? Answer in grams.

Answer 1

Hi Julie.

 

Silver has an atomic mass of 107.87 g/mol.

 

There are 6.022 x 10^23 atoms in one mole of anything.

 

You have 6874 x 10^23 atoms of Ag.

 

So:

 

6874 x 10^23 atoms * 1 mol/(6.022 x 10^23) atoms * 107.87 grams Ag/mol

 

= 123,131.6 grams Ag

 

Hope this helps.
