A 13.0 mL sample of an unknown HClO4 solution requires titration with 25.2 mL of 0.180 M to reach the equivalence point.
What is the concentration of the unknown HClO4 solution? The neutralization reaction is as follows:
HClO4 +NaOH ===>> H2O +NaClO4
Since the reaction is 1:1 you may use the simplified formula of mL x M = mL x M
