Maybe some of you can help me out with these!

Batman uses pellets, not identified, to neutralize the acid in the tank into which he falls: neither are we given the size of the tank. Suppose that the pellets are NaOH and that the tank is 3.05 meters in diameter filled to a depth of 1.25 meters with 98% sulfuric acid by weight. Perfrom the following calculations.

1. Determine the volume (in cubic centimeters) of the aicd in the tank. Volume of the cylinder is pie X r squared X height.

2. Sulfuric acid has a denisty of 1.84 g/cubic centimeters. Determine the mass and numbmer of mokes of acid in the tank.

3. Write the balanced equation for the neutralization reaction between NaOH and H_2_SO_4_ (sulfuric acid). Determine the number of moles and mass of NaOH required to neutralize the acid in the tank.

4. The heat of formation of water by the reaction of a strong acid and a strong base is -57.3 kJ/mol. Determine the heat in kJ released during the neutralization reaction in #3.

5. Suppose the initial temperature of the acid bath is 20°C, and the heat capacity of the reacting solution is 4.18 J/g°C. Determine the final temperature of the bath.

6. After water reaches its boiling point, an additional 2257 J/g s required to vaporize it. Determine the mass of water that is vaporized. What volume will it occupy at 100.0 °C when p=750 torr?
