Question:
A 0.9826-g sample containing dimethyl phthalate, C6H4(COOCH3)2 (194.19 g/mol), and unreactive species was refluxed with 50.00 mL of 0.1104 M NaOH to hydrolyze the ester groups (this process is called saponification).
After the reaction was complete, the excess NaOH was back-titrated with 23.33 mL of 0.1597 M HCl. Calculate the percentage of dimethyl phthalate in the sample.

I graduated in 2018 with a Bachelor of Science degree in Psychology from Dalubhasaan ng Lungsod ng San Pablo. I tutored students in classes and out of classes. I use a variety of strategies to tutor students that include: lecture, discussions about the subject matter, problem solving examples using the principles of the subject matter being discussed in class , homework assignments that are directed towards reinforcing what we learn in class , and detailed practice problems help students to master a concept. I also do thorough research on Internet resources or textbooks so that I know what students need to learn in order to master what is being taught in class .
