Answer:
The number of formula units of silver nitrate is [tex]4.61\times 10^{24}[/tex].
Explanation:
Moles of silver nitrate = n = 7.65 mol
1 mole = [tex]N_A=6.022\times 10^{23}[/tex] atoms/ molecules/ ions
Let the number of formula units of silver nitrate be N.
[tex]N=n\times N_A[/tex]
[tex]N=7.65 mol\times 6.022\times 10^{23}=4.61\times 10^{24}[/tex]
The number of formula units of silver nitrate is [tex]4.61\times 10^{24}[/tex].
