3.45 Liters of the solution is formed.
293 grams of Silver nitrate is approximately 1.724 moles( 293 g/170 g/mol, Molar mass of Silver nitrate is approximately 170 with rounded number).
Then Molarity = Moles/Liters, In order to obtain the liters divide the moles by the molarity
1.724/0.5 = 3.45 Liters
