Question

42.55mL of a standardized 1.005 M NaOH solution was necessary to exactly neutralize 30.0mL of an aqueous H2SO4 solution of unknown concentration. What is the molarity of the H2SO4 solution?
H2SO4 + 2NaOH ==> Na2SO4 + 2H2O

mols NaOH - M x L = ?
Using the coefficients in the balanced equation, convert mols NaOH to mols H2SO4.

Then M H2SO4 = mols H2SO4/L H2SO4
