If you titrate a 25.00 mL sample of H2SO4 with your standardized base and 18.94 mL of base is required for complete neutralization, what is the molarity of H2SO4?

Question

The standardized base has a concentration of 1 M. This means 0.01894 mol of base were used in the titration. This also means that 0.01894 mol of acid were neutralized. However, keep in mind that two protons are produced from every molecule of H2SO4, meaning 0.01894/2 = 0.00947 mol of H2SO4 were initially used.

If the volume was 25 mL, the concentration of H2SO4 was 0.00947/0.025 = 0.3788 M
