Homework Help: Chemistry

Compare the g/L solubility of CaCO3 in pure water, a H3O+ (aq) solution with a PH of 3.00 and a H30+(aq) solution with a pH of 1.00.
Ksp for CaCO3 is 3.36 x 10^-9
CaCO3 (s) + H3O (aq) = Ca (aq) + HCO3 (aq) + H2O (l) (equilibrium equation)
Keq= 71

I knew how to do this for pure water and got
5.8x10-3 g/L
But i dont know how to do this for
Solution with a pH of 3.00 and solution with a pH of 1.00
