Is There Missing Information in the Ksp Equilibria AgCl Data?

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.
