1. The problem statement, all variables and given/known data

What is the maximum [Ca2+] that can exist with 5.2e-4 M c2O4 2- without precipitating? Ksp for CaC2O4 = 2.6e-9.

2. Relevant equations

Well, the Ksp and M is given, I don't know how to apply them.

3. The attempt at a solution

I need help because I missed the lesson.

Thank you.

Pardon? I don't know what you are saying.

If you mean what it is, I don't think I'm supposed to use it since it's not a given in the question.
