To construct a calibration curve we would need to take our stock solution and dilute it to different concentrations. We would then test those different concentration in our spectrophotometer to test their absorbance. If we diluted our samples as follows, calculate the resulting concentrations. (HINT: this is dilution which means we can use M1V1=M2V2, where M1 is our original 150 mM concentration, V1 is the volume of the original concentration that we added water to dilute, M2 is the concentration...
