Chemistry help please?
Here's the question. I will be fine if you only provide the method for solving it.
"A 10.40-mL sample of sulfuric acid from an automobile battery requires 35.04-mL of 2.17 M sodium hydroxide solution for complete neutralization. What is the molarity of the sulfuric acid? Sulfuric acid contains two acidic hydrogens."
I can't seem to figure out how to solve this one. Could someone please guide me in the right direction?

The business about "two acidic hydrogens" is same as looking at the balanced equation:
H2SO4 + 2 NaOH → Na2SO4 + 2 H2O
The point, either way, is that it takes 2 moles of NaOH to neutralize 1 mole of H2SO4.
(35.04 mL NaOH) x (2.17 M) x (1 mol H2SO4 / 2 mol NaOH) / (10.40 mL H2SO4) =
3.66 M H2SO4
