Answer:

Well, silver commonly forms a #Ag^+# cation....

Explanation:

And when it makes music with carbonate anion...

#2Ag^+ + CO_3^(2-) rarr Ag_2CO_3(s)darr#

Wikipedia says that #K_"sp"=8.46xx10^-12# for #"silver carbonate..."#... under standard conditions, and we can use this value to assess the solubility of silver carbonate...

#Ag_2CO_3(s) stackrel(H_2O)rarr2Ag^+ + CO_3^(2-)#...

...for which #K_"sp"=[Ag^+]^2[CO_3^(-)]#

And given the equation....#[Ag^+]=2S; [CO_3^(2-)]=S#...

And so #K_"sp"=(2S)^2S=4S^3#

And (finally) #S_"solubility of silver carbonate"=""^(3)sqrt((8.46xx10^-12)/(4))=1.28xx10^-4*mol*L^-1#

A solubility in …………………………….#g*L^-1=1.28xx10^-4*mol*L^-1xx275.81*g*mol^-1=35*mg*L^-1#...
