Question
Sulfuric was titrated with NaOH solution. 208 mL of .250 M NaOH solution was needed to completely neutralize 65.0 mL of H2SO4. What is the concentration of the sulfuric acid solution?

2NaOH + H2SO4 ==> Na2SO4 + 2H2O
Moles NaOH used = M x L = ??
Moles H2SO4 needed = 1/2 moles NaOH (from the equation).
M H2SO4 = moles H2SO4/L H2SO4.
Moles NaOH used = M x L = ??
Moles H2SO4 needed = 1/2 moles NaOH (from the equation).
M H2SO4 = moles H2SO4/L H2SO4.
