A3 A cup of sea water from Galveston Bay ( containing 3.0 x 104 ppm NaCl. Density for sea water is 1.05 g/mL ) and a cup of soy sauce ( containing 0.8 % ( wt% ) NaCl. Density for soy sauce is 1.1 g/mL ). which one tastes more salty ? Assume Na element is the only contributor for the salty taste. ( Given NaCl : 58.5 g/mol ), and which one has more salinity

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 KOH. An example of such a balanced chemical reaction is shown here: C51H98O6 + 3KOH à C3H5(OH)3 + 3C16H31O2K Triglyceride                                        Soap If, during the saponification reaction, 231.5 g of C51H98O6 is mixed with 231.5 g of KOH and 160 g of soap is produced: Calculate the theoretical yield of soap (in grams), C16H31O2K, and indicate which species is the limiting reactant. Provide your answer to 2 decimal places (5). Calculate the percent yield for this reaction. Provide your answer to 1 decimal place (1). Show ALL steps and equations involved in your calculations. Remember to label all steps clearly and use appropriate units.
