molar solubility

Question:Please explain to me how to do this problem? what did I do wrong? (see below

Question: What is the molar solubility & molar concentration of each ion of Ag3PO4 in water?  Ksp = 8.9 ´ 10-17 

 

Here is my work

 

  • (3x)3 x = 8.9 x 10-17 
  • combine  (3x)3 x to form 9x4 = 8.9 x 10-17  
  • x = 1.27x 10-17 = molar solubility 

 

But I'm Wrong, the correct answer is:

 

Molar solubility: 4.3 x 10-5 

[Ag+] = 1.3 x 10-4  

[PO43-] = 4.3 x 10-5
