the concentration of Ag+ in a saturated solution of Ag2Cro4 is 1.6x10^4 M. what is the Ksp value for Ag2Cro4?
the solubility of BaCO3(s) in water is 4.0X10^5 M. Calculate the value of Ksp for BaCO3

Chemistry ASAP 
DrBob222,
Ag2CrO4 ==> 2Ag^+ + CrO4^2
Ksp = (Ag^+)^2(CrO4^2)
Set up an ICE chart, substitute into the Ksp expression and solve for Ksp.
#2 is done the same way.
Post your work if you get stuck.
