In an experiment of soap, after being dissolved 10 gr Triglyceride in ethyl alcohol, it is reacted with 25 ml of 5 M NaOH solution by stirring until boiling. Then, the reaction is filtered and cooled. After being waited in the oven overnight, the precipitation is weighted, and the obtained amount is nearly 9 gr. (Triglyceride molecular mass: 885.4 g/mol, Soap:306 g/mol)
a.) Calculate theoretical amount of soap
b. Find percentage of yield of soap
c. Calculate % error
