I have a question in my environmental engineering class that goes like this:

if 100mg H2SO4 is added to 1 Liter of water, how many milligrams of NaOH (strong base) must be added to neutralize the acid?

the answer is 81.6mg, but how do i get to the answer?

i tried writing a reaction of: H2SO4 + NaOH = 2H+ + SO2-4 + Na+ + OH-

then doing: molarity of H2SO4 times Molarity of NaOH = 10-7

but i just cant seem to find how to get the answer.

any help would be greatly appreciated

This is a simple stoichiometry. Start by balancing the reaction equation - so far it even doesn't contain correct products, you just dissociated both substances. Do you know how to read balanced reaction equation?
