a serum sample is analyzed for potassium by flame emission spectrometry using the method of standard additions. Two aliquots of serum are added to 5.00 mL portions of water. To one portion is added 20.0 microL of 0.0750 M KCl solution. The net emission signals in arbitrary units are 23.2 and 68.6
What is the magnitude of the emission signal produced by the standard?
