KHP is a monoprotic acid with a molar mass of 204.22 g/mol. The titration data are as following.
The average concentration of NaOH solution is
1 2 3
mass of KHP (g) 2.789 2.543 2.612
vol NaOH used (mL) 27.77 23.22 27.12
You didn't ask a question but I assume you are to calculate the molarity of NaOH.
mols KHP = mols NaOH
mols KHP = g/molar mass
mols NaOH = volume NaOH x M NaOH.
Post your work if you get stuck.
