2.30 g/L = 2.30/333 mols/L = approx 0.007 M but this is an estimate.
..........AB3 ==> A^3+ + 3B^-
I........solid.......0......0
C........solid...0.007...3*0.007
E........solid...0.007....0.021
Ksp = (A^3+)(B^-)^3
Ksp = (0.007)(0.021)^3 = ?
Check my work.

IT doesn't tell me anything. WHAT is incorrect? What number did you get? If you used my numbers I'm not surprised it (the answer you obtained) is incorrect. Did you read where I said it was approximate? Did you work it out from the beginning. Probably not.
