A generic salt, AB, has a molar mass of 293 g/mol and a solubility of 2.20 g/L at 25 °C. What is the Ksp of this salt at 25 °C?

• chemistry -

2.20g/293 = about 0.007 but you need to get a more accurate number.
.......AB ==> A + B
I....solid....0...0
C....solid....x...x
E....solid....x...x

The problem tells you that is is 0.0
07 mol/L. Substitute this into the Ksp expression and solve for Ksp.
