Students are to use information found in Experiment 23 (pgs 25-36) of their CH132L Laboratory Manual, along with the data provided to complete this assignment. Part 1 Introduction: Students should write an introduction that is a minimum of 500 words. The introduction should include at minimum a brief discussion on the following topics. Part 2 Data Analysis: Students should use the information found in Experiment 23 (pgs 25-36) of their CH132L Laboratory Manual to complete Table 1. Each sample was made with a 0.400M NISO4 6H2O stock solution and has a final volume of 50.00 mL. With the completion of the Table 1, the student will then construct a calibration curve, solution concertation versus absorbance, in Excel or similar program. The graph should display the trend line, data table, axis titles including unit, chart title and student name. The graph and with trend line will be submitted with this assignment. Table 1. (1) Why is it important to graph data? (2) Discuss the mathematical relationship between density and concentration. (3) What is the importance of accuracy in this experiment? (4) What is the importance of the calibration curve and what information does it provide.
