Hello, help on any of these questions would be greatly appreciated

3. Would a precipitate form in a solution what is 3.4 x 10^-4 mol/L K2CrO4 and
4.8 x 10^-5 AgNO3?.
 found the Qsp but is there a way to find the Ksp or does it have to be given?

4. what mass of NaOH would be required to cause a precipitate i a 10.00 ml sample of 0.10 mol/L Mg(NO3)2.

- Thanks for the help

K_sp values are tabelarized.
