An experiment wаs perfоrmed tо investigаte the reаctiоn between Zn metal and Ni2+ (aq)at different concentrations. Because the Ni2+ (aq)ion is green, the extent of the reaction was determined using spectrophotometric analysis. Four 20.0 mL standard solutions of Ni2+ (aq) were prepared by dissolving NiCl2 ⦁ 6H20 (molar mass 240 g/mol)) in water. The absorbance of each solution was measured; the results are shown both in the table below and in the following plot of the absorbance data. Solution [Ni2+] Absorbance 1 0.020 0.12 2 0.040 0.25 3 0.060 0.39 4 0.080 0.51 The figure shows a graph of four data points in a coordinate plane. The horizontal axis is labeled “Concentration, in moles per liter,” and the numbers 0 through 0.10, in increments of 0.020, are indicated. The vertical axis is labeled “Absorbance,” and the numbers 0 through 0.6, in increments of 0.1, are indicated. The coordinates of each data point are as follows. Note that all values are approximate. Data point 1: 0.020 comma 0.12. Data point 2: 0.040 comma 0.27. Data point 3: 0.061 comma 0.39. Data point 4: 0.082 comma 0.51. What is the expected absorbance of a standard solution made by dissolving 0.0070 mol of NiCl2 ⦁ 6H20 in water to make 100. mL of solution?
