Q5. As part of the aspirin synthesis lab, the orgo students also had to perform the following calculation to demonstrate their knowledge. Are you able to help them work this out?Saponification is a process in which soap is produced from the chemical reaction between animal fat (triglycerides) and a strong base such as NaOH. An example of such a balanced chemical reaction is shown here:C57H110O6 + 3NaOH à C3H5(OH)3 + 3C18H35O2NaIf, during the saponification reaction, 228.5 g of C57H110O6 is mixed with 211.7 g of NaOH and 180 g of soap is produced: a. Calculate the theoretical yield of soap (in grams), C18H35O2Na, and indicate which species is the limiting reactant. Provide your answer to 2 decimal places. b. Calculate the percent yield for this reaction. Provide your answer to 1 decimal place. Show ALL steps and equations involved in your calculations. Remember to label all steps clearly and use appropriate units

The O'Keefe's have 50 gallons of cucumbers for pickling. They have supplies of potassium hydroxide, sulfuric acid and ethanol on hand. The 1.5M KOH solution costs $5 per liter, 9 M H2SO4 solution costs $7.50 per liter, and ethanol costs $25 per liter. A 50 g jar of alum from the grocery store costs $8.59. Do you think it’s worth the time and trouble for Richard and Diane to make their own alum from discarded aluminum cans? Explain your answer showing all calculations
