Concentration of the ${\rm{A}}{{\rm{g}}^ + }$ ions in a saturated solution of ${\rm{A}}{{\rm{g}}_{\rm{2}}}{{\rm{C}}_{\rm{2}}}{{\rm{O}}_{\rm{4}}}{\rm{ \;is\; }}2.2 imes {10^{ - 4}}{\rm{ mol\; }}{{\rm{L}}^{ - 1}}.$ Solubility product of ${\rm{A}}{{\rm{g}}_{\rm{2}}}{{\rm{C}}_{\rm{2}}}{{\rm{O}}_{\rm{4}}}$ is

A 20-litre container at 400 K contains ${\rm{C}}{{\rm{O}}_{\rm{2}}}{\rm{(g)}}$ at pressure 0.4 atm and an excess of ${\rm{SrO}}$ (neglect the volume of solid ${\rm{SrO}}$ ). The volume of the containers is now decreased by moving the movable piston fitted in the container. The maximum volume of the container, when pressure of ${\rm{C}}{{\rm{O}}_{\rm{2}}}$ attains its maximum value, will be
