5. In Part 2, you constructed a calibration curve using standards ranging from 0.010 M Cu(NO3)2 to 0.10 M Cu(NO3)2. Suppose your TA gives you a cuvette containing a Cu(NO3)2 solution of unknown concentration and asks you to analyze it. Your TA is kind enough to give you a hint: the unknown solution has a concentration between 0.14 M and 0.19 M. How would you analyze this unknown solution?
