A student prepares a caffeine standard solution that has a concentration of 1858 ppm. To prepare a calibration curve, the student pipets various volumes of the standard solution into 50.0 mL volumetric flasks and dilutes to the fill line with water. The absorbance of each solution is measured in a 1.00 cm cuvette using the spectrophotometer and is shown in the table below. Calculate the concentration of each solution and create a calibration curve using the absorbance data provided. Based...
