Calculate the molar solubility of BaSO4 in a solution in which [H3O+] is 2.5 M.
I can almost solve this on my own. If you know the following equations:
BaSO4 = Ba2+ + SO42
SO42 + H+ = HSO4
HSO4 + H+ = H2SO4
and I know [H+] = 2.5 M
along with the following equation:
[Ba2+] = [SO42] + [HSO4] + [H2SO4], I should be able to solve this, but I feel like I'm still missing something. Please help.

No, I think you have it all. I would correct the last equation by deleting the H2SO4. You may not need the third equation from the top since the first ionization of H2SO4 is 100%.
