Provide a concise explanation of Mass spectrometry (MS) in regard to food samples. include the specific application name (e.g., Identification andQuantification of Mercury in Salmon), outline a brief description of samplepreparation procedures, and provide a summary of the obtained results from the analytical process

In Part A you will be performing several mass measurements. What are two precautions you must observe when using the electronic balance?

The mass of the original mixture was 2.03g. The combined mass of the salt and the evaporating dish was 48.92g with the tare mass of the evaporating dish being 47.98g. The combined mass of the sand and watch glass and filter paper was 32.15g with the tare mass of the watch glass being 30.91g and of the filter paper being 0.28g. 1A) calculate the mass of the table salt recovered. 2A) Calculate the mass of sand recovered 3A)calculate the total mass of table salt and sand recovered.  4A)Calculate the percent table salt in recovered material. 5A) calculate the table salt in the original mixture.

A student was able to separate the three components of a mixture via liquid chromatography. She obtained 1.27 g1.27 g of component A, 0.950 g0.950 g of component B, and 0.260 g0.260 g of component C. Determine the mass percent of each of the three components in the mixture.

4. A new procedure for the determination of sulfur in coal was tested on a standard coal sample with a certified value of 2.14% sulfur by mass. The new procedure gave results of 2.11%, 2.07%, 2.04%, 2.06%, and 2.16% for five separate determinations.  a) Does the new procedure give the correct result at the 95% confidence level?  b) Does the new procedure give the correct result at the 90% confidence level?

Supply the missing information in the table. (Given in Blue). Answers in scientific notation should be in this sample format >>> 1.0 x 10-14

Question 4. In the course material you have been introduced to multiple charging for electrospray spectra. 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. 659.8 714.7 779.5 857,4 952.6 1071.5 BMW Sp
