Calculate the quotient #"mass"/"molar mass"# for the molar quantity...

Explanation:

And here, we have #(0.648*g)/(107.9*g*mol^-1)=6.0xx10^-3*mol#.

Given that the #"Avocado number"-=6.022xx10^23*mol^-1#, can you tell me that NUMBER of silver atoms that constitute such a mass. You have all the data to do so............
