Drink mix concentrations and absorbances for constructing a standard curve Concentration (MM) Concentration (M) Absorbance 134 0.134 1.22 Sample 1 97 0.097 0.88 Sample 2 256 0.256 2 33 Sample 3 77 0.077 0.70 Sample 4 (1 pts)
Plot your data of absorbance versus concentration (in M) using Excel. Add a trendline and display the equation of the line to determine the slope and yintercept. Please review the video on using Excel if needed Enter the slope of the trendline (1pts)
Enter the yintercept of the trendine (pt)
Using the mola absorptiwny (sopa) determined from your plot, calculate the expected concentration (in M) of a drink mix (1 pts)
Select the statement the best answers the following question
Can you use your plot to predict the absorbance of a 214 mM solution of nickelo) chloride and why?
A Yes, because the same instrument is used for the measurement of the new compound.
B. Yes, because you can use the same cuvette for the measurement of the new compound
C. No, because the determined absorptivity apples only to the compound measured
D. No, because the detector works differently depending on the compound measured
