moles KHP = grams/molar mass
You are titrating one H with one OH; therefore, moles NaOH must be the same as moles KHP.
moles NaOH = M x L.
YOu know moles NaOH and volume (in mL, convert to L and volume = difference in final buret reading - initial buret reading). Solve for M
A solution of sodium hydroxide is standardized against potassium hydrogen phthalate (KHP, formula weight 204.2 g/mol). From the following data, calculate the molarity of the NaOH solution: mass of KHP 1.234 g; buret reading before titration 0.23 mL; buret
reading after titration 48.87 mL.
Answer in units of M.
