PRACTICE: Prepare the following graph and perform calculations on a separate sheet of graph paper or in your laboratory notcbook. Prepare a graph of the following data: [CoCl (M or mol/L) I. Absorbance 0 0 0.015 0.21 0.030 0.48 0.045 0.68 0.060 1,06 0.075 L10 0.090 1.35 2. Calculate the slope of the line for the relationship in the form of Beer's Law: A-kICoCl] (Don't forget the units!) 3. What is the concentration of an unknown CoCh solution with an absorbance of 0.516? 58 Skyline College Chemistry 210 Laboratory Manual (August 2013 Revision)
