I have discovered a new chemical compound with the formula A2B. If a saturated solution of A2B has a concentration of 4.35x104M.
a) What is the concentration of B2 ions?
b. What is the concentration of A1+ ions?
c. What is the solubility product constant for A2B?
Can you please show me how to do all of these problems if you know the concentration of the solution.

Reason your way through it. I assume A2B is a solid.
.........A2B > 2A^+ + B^2
.....4.35E4M....x......x
For every molecule of A2B that dissolves, you must have two (2) ions of A^+ and one (1) ion of B^2; therefore, for every 4.35E4 mols A2B that dissolve, you must have 2*4.35E4 mols A^+ and 4.35E4 mols B^2. right?
Then Ksp must be (A^+)^2(B^2) = (2*4.35E4)^2(4.35E4) = ?
