concept that seemed difficult to you at first, but then after working on the concept, you were able to master it. Include a description of what made the concept difficult at first, and then discuss what you did in order to better understand the concept. If you are not familiar with The Onion, it's a satirical newspaper. That "NSF: Science Hard" article pictured above came out while one of my colleagues was in college. She said that it made her laugh so hard because she was in the middle of a very hard time analyzing data. But, She made it through. And you can make it through this course!

The goal is to convince an investor to invest in your company so that you can build a factory to make ester compounds. For example, you could make hexyl pentanoate, and sell it for use in perfumes and make the investor money. You must come up with a compound that you can make and sell. You can use your textbooks and theinternet as resources. You can also access the link: https://jameskennedymonash.wordpress.com/2013/12/13/infographic-table-of-estersand-their-smells/ to look at an infographic of the ester compounds responsible for the smell of different fruits, perfumes and flowers. At the end of your research, you must have the compound table filled out
I know you don't answer graded questions and I am not looking for you to straight up give me the answer to this but how do I even start? like I said before I know that the highest peak is 16amu which is Oxygen but do I just the vertical bar as a ratio? Like the next bar to the left (15amu?) is like 90% intensity? so like 9:10 ratio? There isn't even a 15amu element so please just give me some idea where to start. The place in the book it tells you to go to read has nothing about this stuff, its about finding empirical formulas from mass or percentages.... please help me!

Congratulations, you have just been hired at a local laboratory. Your first task is to prepare 10.0 mL of a 1.50 x 10-6 M solution of a small protein (FW: 3600 g/mole). Available to you are an electronic balance that is accurate to the nearest 0.001 g, a 1.00-mL pipette, and 10-mL volumetric flasks. Describe how to prepare the desired solution. (Note that the amount of protein is so small that you will need to make a more concentrated stock solution and dilute it.)
