Answer:

We know that in #126.94*g# of silver there are #N_A", i.e. Avogadro's number of silver atoms, "6.022xx10^23" individual silver atoms"#.

Explanation:

So, we work out the quotient, and multiply by Avogadro's number,:

#(3.84*g)/(126.94*g*mol^-1)xx6.022xx10^23*mol^-1#

#=# #??" silver atoms"#
