Is There Missing Information in the Ksp Equilibria AgCl Data?

Click For Summary
SUMMARY

The forum discussion centers on the missing information in the Ksp equilibria data for AgCl, specifically the volume of the initial solution. Participants agree that without this volume, calculations regarding the precipitation of halogen ions become ambiguous. The consensus is that the problem is incomplete, as the Ksp values alone do not provide sufficient context for determining the order of precipitation. One user highlights that an initial volume of 2.4x106 L would result in no precipitate, emphasizing the necessity of this data for accurate analysis.

Please look at attached picture.

So, I tried solving it. Apparently, the answer is C. But, I think there is missing information (ie the volume of the initial solution). Care to back me up on this?

I back you up. Without knowing the volume of the solution, you could have these halogen ions dissolved in an ocean of solvent.

Maybe they meant to assume no change in volume.
 
Yellowflash: I tried it, but it gave me B) as an answer (2.58 g more precisely). I'm not sure I did all the steps correctly though.
 
It is intended to be a limiting reagent question, with Ksp values given only to help in determining the order of precipitation. But yes, it is incomplete. If the initial volume is 2.4x106 L there will be no precipitate at all. We are not talking about some absurd volumes, 2.4x106 L is almost exactly olympic-size pool.
