**A 25.00-mL sample of an unknown HClO4 solution requires titration with 22.62 mL of 0.200 M NaOH to reach the equivalence point. What would be the concentration of NaOH in the final solution if no reaction occurs? Report your answer to three decimal places.**

**Answer:**

Molarity, m1*v1=m2*v2

molarity = m volume = v

v1 =22.62 m1=.2

v2=25+22.62

22.62*.2=(25+22.62)m2

solve for m2 to find .095
