At 25 °C, only 0.0340 mol of the generic salt AB is soluble in 1.00 L of water.

What is the Ksp of the salt at 25 °C?

AB(s)↽−−⇀A+(aq)+B−(aq)

I get .0012 but that is wrong apparently. Help please!

When you post a question like this it would help if you showed how you did the problem. As it is, I'm forced to guess what's wrong. Here's my best guess. The number of 0.0340 has three significant figures (SF) in it so you should have three in the answer. You have only two. Recalculate and round to 3 s.f.
