Question

Use an acid-base titration to calculate the molar mass of an acid.
A 0.8699-g sample of an unknown monoprotic acid is dissolved in water and titrated with standardized sodium hydroxide. The
equivalence point in the titration is reached after the addition of 31.87 mL of 0.2852 M sodium hydroxide to the sample of the unknown
acid. Calculate the molar mass of the acid.

Expert Solution

Introduction

mass of the acid = 0.8699 g

molarity of NaOH = 0.2852 M
volume of NaOH = 31.87 mL = 0.03187 L

At the end point,
moles of NaOH = moles of the monoprotic acid
