Titration of 15.0 mL of an NaOH solution required 7.4 mL of a 0.25 M KNO₃ solution.What is the molarity of the NaOH solution?

The titration involves NaOH and KNO3, but KNO3 is not an acid or base, so it doesn't react with NaOH. The question seems incorrect as KNO3 is not used for titration with NaOH. Assuming a typo and it should be HCl instead of KNO3, use M1V1 = M2V2. M1 = (0.25 M * 7.4 mL) / 15.0 mL = 0.12 M.
