Silver Chromate Solubility Precipitation

Answer the Questions based on Ag2CrO4 (Silver Chromate) and Ag3PO4 .
Silver Chromate dissociates in water according to the equation.
Ag2CrO(s)<->2Ag+ CrO4 Ksp= 2.6x10^-12 at 25 deg C.
a) Write the equilibrium constant expression for Ag2CrO4 (Silver Chromate)
b) Calculate the concentration, in mol L-1 of Ag in a saturated soln of Ag2CO4 at 25 deg C.
c) Calc the maximum mass, in grams, of Ag2CrO4 (Silver Chromate) that can dissolve in 100.0mL of water at 25 degrees C.
d) A 0.100mol sample of solid AgNO3 is added to a 1.00L saturated solution of Ag2CrO4.Asumming no volume change, does [CrO4] increase, decrease, or remain the same?
In a saturated solution of Ag3PO4 at 25 degrees. C, the concentration of Ag is 5.3x10^-5.the equilibrium constant expression for dissolving of Ag2PO4 in water is shown below.
Ksp=[Ag]^3 [PO4^-3]
e) write the balanced equation for the dissolving of Ag3PO4 in water
f) Calc the value of Ksp for AG3PO4 at 25 C.
g) A 1.00L sample of saturated Ag3PO4 soln is allowed to evaporate at 25 degrees C to a final volume of 500mL. What is [Ag+] in the solution? Justify your answer.
Note!! We only need d and g worked out. I again gave you the rest of the problem so you could use it if you need it.
