- 4/3 pie * (0.0576/2)^3=0.00010061=1.00=1.00x2.20/60.02=0.036654449*60.09=2.202565811=2.2E-18 ? is this even right? i've been struggling with this problem for hours.A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of methyl acetate, chloroform, ethanolamine, diethylamine, and tetrahydrofuran. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid methyl acetate chloroform ethanolamine diethylamine tetrahydrofuran density 0.93 g ml 1.5 g ml 1 -1 1.0 g ml 1 0.71 g ml 0.89 g ml. Next, the chemist measures the volume of the unknown liquid as 1005. cm' and the mass of the unknown liquid as 1.49 kg. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Given the data above, is it possible to Identify the liquid? If it is possible to identify the liquid, do so. 0 gml. yes no methyl acetate chloroform ethanolamine…Give explanation of correct option and explanation of the incorrect options. Not hand written please.

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.
