3. what is the equation of the line for your calibration curve?

4. using the equation for the line for your calibration curve, calculate the absorbance of an unknown solution if it has molarity of 3.75 x 10-3 M.

5. use the data for one of the standards and the cuvette path length (1 cm) to determine the molar absorptivity for this compound. you should use equation 4 (beer-lambert law). be sure to include units

6. using your equation from #4 above, what would be the molarity of a Co(NO3)2 * 6H2O solution, analyzed under identical conditions as in this experiment, if its absorbance is 0.254
