Question

How would I find the molarity of NaOH based of this data? I dont know if you need to know that the molarity of KHP is .023319.

Explanation / Answer

1 mole of KHP reacts with 1 mole of NaOH

Trial #1,

moles of KHP reacted = 0.023319 M x 19.6 ml = 0.46 mmol

moles NaOH added = 0.46 mmol

volume of NaOH to reach equivalence point = 3.0 ml

molarity of NaOH solution = 0.46 mmol/3 ml = 0.153 M

Trial #2,

moles of KHP reacted = 0.023319 M x 19.75 ml = 0.46 mmol

moles NaOH to reach equivalence point = 0.46 mmol

volume of NaOH to reach equivalence point = 3.0 ml

molarity of NaOH solution = 0.46 mmol/3 ml = 0.153 M

Average molarity of NaOH = 0.153 M
