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

Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.
