Thanks so much for the help! It's great to have people out there willing to lend a helping hand, or keyboard LOL

Going through my textbook there isn't anything to explain this to me simply. Can anyone help? What is the [H3O+] of a 2.0M solution of the weak acid HA? Ka=1.8x10^-7

I am a "virtual student'' in my school without a teacher and I need some urgent help with a question not covered in my textbook or other assignments. The question is: what is the solubility in g/L of AgI in a 0.040 M solution of MgI2 Ksp for AgI is 8.3 x 10 (to the power of -17) I have no idea where to start on this one and any help is greatly appreciated
