In a modified version of the unknown acid analysis experiment, a 0.7032 g sample of unknown monoprotic weak acid was dissolved in water using a 100-mL-size volumetric flask. A 10.0 mL aliquot of this weak acid solution was titrated with a 0.0498 M NaOH solution. The equivalence point was reached by adding 11.62 ml of NaOH from the buret. What is the molar mass of this unknown acid?
