Chapter L1, Problem 16CTQ

Each peak in the spectrum below can be used to provide a measure of the mass of this protein, you can work out the charge associated with each peak, and measures can be averaged to find the overall mass. Use simultaneous equations to find the charge associated with each peak in the spectra below, which will allow you to calculate the average mass of each species. Include an estimate of the error associated with this measure. Dont use chatgpt

Please don't provide handwritten solution.....    Please draw stereographic projection of 4/m 3 2/m and m 3 m. Mark the intercepts and draw your conclusions. Compare and contrast both point symmetries.

What are the advantages of using the KBr in IR spectroscopic sample preparation?  Please shortly answer at your own words. Answer should be to the point (specific 4-5 lines).

What would be the multiplicity associated with peak 2?

23. Consider the mass spectrum of hexane. Relative Intensity 100 80 60 40 20 O a. b. C. d. e. f. g. 10 MS-NW-5505 50 m/z Label the [M] peak. What is the value of m/z associated with this peak? 20 30 40 60 70 What is the mass of a hexane molecule that contains six ¹2℃ atoms (¹2CH3-¹2CH₂-¹2CH₂-¹2CH₂-¹2CH₂-¹2CH3)? Does this fit with the m/z value reported in part a of this question? 80 Draw a picture, like the one of "all ¹²C hexane" above, of a molecule that can account for the existence of a peak at m/z = 87 in the mass spectrum of hexane. (Check your work.) There are actually three acceptable answers to the previous question because there are three unique locations in a hexane molecule to replace a ¹2C with a ¹3C. If you have not already done so, draw the other two acceptable answers to the previous question. The peak at m/z = 87 is called the [M+1]* peak. Construct an explanation for this name. Use your periodic table to calculate the weight, in grams, of 1 mole of hexane to four…
