11 of 11 I Review | Constants Periodic Table Suppose that you want to construct a line with slope m = 3 that passes through the point (2, 1). You would begin by setting up the equation y = 3x +b If you plug in the coordinates for any point on that line, the two sides of the equation will be equal. Once you've done this, you can solve for b. What is the value of b? Express your answer as an integer. > View Available Hint(s) 8:59 PM 41% 67°F x口ツ 8/31/2021

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
