The concentration of a naoh solution was experimentally determined by dissolving 0.7816 grams khp (204.2212 grams/mol) in 50.0 ml of water and titrating the sample with 40.82 ml of the naoh (40.000 grams/mol) solution. the concentration of the standard naoh solution is

The concentration of the standard NaOH solution is 0.094 moles/L.

Explanation:

In the titration, the equivalence point is defined as the point where the moles of NaOH (the titrant) and KHP (the analyte) are equal:

     moles of NaOH = moles of KHP

The is 40.82mL = 0.04082L and the moles of KHP are

Replacing at the first equation:

a is the correct answer

i think it's letter a.
