can someone please help me with these problems? i have no idea what's going on in my chem class and the teacher doesn't really explain it well. Thanks!

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

the Ksp of Ag2CO3 is 8.1x10-12. what is the molar solubility of silver carbonate?

what would be the concentration of chromate ion in a saturated solution of CaCrO4 (Ksp= 7.1x10^-4)
