help!!!

my tank was way to contaminaited so i needed to replace the acid, so i bought a gal of H2SO4 industrial grade 98% pure and acording to my calculation it was needed 9.56gals of water to have a solution of 9.3%concentration i did the solution in the tank yesterday, and it was a really exotermic reaction, the bad thing is that today it still warm, i believe over the 30C.
need help in the calculations please, i know 9.3% is not the LCD ratio used, but i want to have a couple of different concentrations for a couple of experiments, please help me on the ecuations because im not the brighter on chemestry.
by the way the concentration is by volume

Strong acids react with the addition to water. Hopefully you didnt add the acid first or it would have spit acid everywhere and probably melted your tank. A 3:1 ratio is water : battery acid(a mix of 1/3 sulfuric already). So roughly 9 gallons of water to every 1 gallon of acid. Allow it to cool and try to do a batch with it.

Now that you have it partly mixed it's going to be even more difficult to figure out how to get where you want to be. I've always used a car battery hydrometer to measure new solution. It's about a specific gravity of 1100 for the LCD solution. Some will say this is not accurate. It's always worked for me. It may be less accurate for used solutions due to desolved contaminents if you are trying to replace evaporated water.
