PLEASE DO A B AND C THANK YOU SOOO MUCH!!!!!!!!

Course: Logical MathematicsFran and Juan Carlos have finished analysis of 112.5 GRAMS of sediments they collected at mouth of a river, and have spent 5 minutes for every 20 MILIGRAMS (MG) of minerals.How many MINUTES did they spend in total for 112.5 GRAMS? (Remember that 1 GRAM = 1,000 MG).  Please details of procedure

Answer the questions using one of the words or phrases from the following list. We suggest that you copy and paste answers as it avoids mis-spellings and typos. Accuracy Precision False positive False negative Detection limit Blank Linear range Spike Limit of quantitation Internal standard Please provide the terms for each definition If a patient does not have COVID, but a test results says that they do? How close your experimental result is to the "true" answer? When you run an unknown and then repeat the analysis after adding a known amount of analyte? When you run a solution known to have a zero concentration of your analyte? The lowest concentration of an analyte which can be reported with an accurate concentration? If a patient does have COVID, but a test results says that they do not? How close multiple sample replicate results are to each other? When you run a solution with a known concentration of a compound which is not your analyte? The lowest concentration of an analyte…

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. Check samples also need this type calculation
